the very next question seems to have an error:

Q: A car consistently travelling at 60 mph from standstill will have travelled 60 miles in one hour

TRUE / FALSE / CANNOT TELL

I say its cannot tell as we dont know the road conditions, but the answer is:

FALSE: the car will have averaged a speed of 30 mph and so will only have travelled 30 miles.

The next question is: A car consistently accelerating at 60 mph from standstill will have travelled 120 miles in two hours

A: TRUE - the car will have averaged a speed of 60 mph and so will have travelled 120 miles.

im guessing the first question has errors, but really? that many'?
