I was thinking of the same thing, why bother about the refilling part when it can be done at any time. Thus the calculation comes up with the same result as quoted.Quote:

i aint doing math no sir lol
refilling can only be done if the car is empty, not just when ever.Quote:

4. What sort of fuel?
5. What color is the car?
The question is not null and void there is rocket cars, I watch them race at least once a month at the local Drag strip.Quote:

And I must say the shock wave created is beautiful, I love the feeling of it :D
Here is a picture taken by me last year of the rear of the jet car. I also have a video of the Jet Car on youtube if you want to check it out. Just search "Jet Car Napierville"

they go fast but they don't fly
Face it toward the sky instead of down a track and it does, its the same a rocket except they point them down a track not upwards?!?!Quote:

Only a spoiler at the back like a car, they way they are shaped creates the downward force to keep them on the track.Quote:

See no wings just a spoiler, this is "Ice Storm" Jet Car

Astra and Zenrax are both wrong.
Its not the speed that allows a rocket to clear the earths graviational field. Its thrust, which is unspecified and irrelevant to the question.
Cut-Down!!!
yeah, come on guys, the car definitely leaves orbit. she clearly says the car goes 100kph. it can therefore be assumed that the acceleration is variable dependent on the requirements needed at any given time to propel the car out of orbit at 100kph. my guess is that we are also supposed to assume that some sort of secondary propulsion is used to keep the car 'fixed' as well as stopped so that it doesn't fall back to earth some every time it stops.
I think the really appalling part of this question is the abhorrent disregard for significant figures. 12th decimal place? really? assuming the answer is in the thousands of hours range, that requires an answer with 16 significant digits when the most you have given us in the variables is 6! There is no way to be that accurate with the data given.
also, as far as the jet engine cars are concerned, jet engines are not rockets, at least not from my understanding. Jet engines still require atmospheric oxygen to operate whereas a rocket has all the required oxygen mixed into the fuel. That is why we don't send jets to space, we send rockets...
There actually IS a tiny bit of data missing here...
Is the road a scenic route, or is it a toll-road? :rolleyes:
They are both made exactly the same way and work exactly the same way except that a "Rocket" requires two tank liquid oxygen and Fuel, a Jet car only requires one for the fuel bcs there is an abundant amount oxygen on earth but Jets are still able to travel into space just not for long periods of time. Some jets do, take a look ;)Quote:

Gonna start setting up equation, then solve later.
Q. The moon is 384 000km away from the Earth. A rocket car that can travel at a speed of 100km/h is traveling there.
A.
384,000 km / (100 km/h) = 384 hr
Q.
The car has a fuel tank of 450 L which is the amount the car starts off with, and uses 15L of fuel per hour when moving but can refill it for 17 L per hour when the amount of fuel has dropped to zero.
A. Setting up equations for fuel tank:
Let y = amount of fuel in tank
Let t = hours
y = 450 - 15t when y > 0
y = 450 +2t when y < 0
Q.
The car's maxinum durability is 2586 and loses 13 durability per hour but can fix it up to maxinum durability within 3.1 hours but only if it does it for exactly 3.1 hours meaning if it stopps during the 3.1 hour period, the car's durability isn't increased. The car starts off at maxinum durability as well.
A. Setting up equations for durability:
Hp = 2586 -13x when hp > 1
Hp !< 0
Q.
When the car's durability and fuel have both dropped to zero the fuel is refilled first and the durability next. But when durability drops while refueling the car- the car continues to refuel instead. Also, if a car has lost fuel or durability, it stops at that moment.
During the trip, 300 000 km is within the Earth gravitational field and the car gains a -24% speed boost, 15% fuel refill boost and a -33 percent car fixing time. For the other 30 000 km, the car gains a 10% speed boost, -45% fuel refill boost and a -20% car fixing time. For the rest 54 000km, the car gains a -5% speed boost, 7% fuel refill boost and -12% car fixing time.
A. Setting up time variables
total x = 384 000 km
When x< 300,000,
v = (100 - 24) = 76 km/h
y = 450 - 15t when y > 0
y = 450 + [-15 + (19.55) t ] when y < 0
Hp = 2586 -13x when hp > 1
Hp !< 0
(to do, need equation relating everything to time)
How long will it take for the rocket car to reach the moon?
But what if I'm in Server 4? Do I still get the prize? And shouldn't it be title improbable question?
Here's my first answer. If its not correct then I have one more approach to try.
8616.823885905293hrs= 359days, 49minutes, 25.9892590548seconds.
how do u send people resources?
how about this...
199days 12hours 31minutes 0.280813391224seconds
as long as you always fix it after refuling is complete, it never stops moving, so its just a pure distance calculation:
300,000km at 76km/hr
+ 30,000km at 110km/hr
+ 54,000km at 95km/hr
4788.5167464114832535885167464115 hrs
I already posted that answer critta :]
So, did she pass her algebra test or not??
Kittiana, did you get the resources Gloria promised?
I don't know if glorias seen this thread since she last posted, what with people being really negative and awkward than actually working it out, so no, no resources. Not that i'm bothered, I just want to know the answer ^_^
do your own homework =='
the answer to the question is 42
no no no, you people are all wrong! The answer to this hellishly impossible question is 666!
42, the answer to life the universe and everything! ;D
