measuring distance using Ek and Ep??!

okay, so the problem gives the following information
a car(1 tonne) is travelling at 75km/hr, up a hill. Assuming gravity is 9.8ms-2 , how far will the car travel?

so far ive done:
Ek= (.5 x m x v^2)
Ek= 36450000J

36450000=m x g x h
36450000=9800 x H
36450000/9800= H
H= 3719.38m

is this correct?

It would help if one shows the substitution of the values.

1/2 mv2 = 0.5 * 1000 kg * (______ m/s)2? Make sure units are consistent.
