Hey guys!,

I've been given a test assignment and there's one really simple problem that I've been staring blindly at for some time now:

"The distance that a car can travel on 1 litre of gas at the velocity km/h is given by:

In one hour, driving at a constant speed, the car used 7 litre of gas. How fast was it driving?".

Now, I know that this is really simple, but I think my brain turned to mush a few hours ago. I've been asked to calculatev, given a function where the value is distance traveled on 1 litre of gas.

Can anyone give me the first step, please?

Cheers.
