Answer 1

hey mates your answer is here

Since it is time based, the car would have to teleport. Thank you for pointing out my mistake.

Its impossible since the first journey is 60 miles with an average speed of 30 mph- so the car travelled for 2 hours. In order for the car to average 60 mph over 120 miles, it would have to travel for exactly 2 hours (120/60). Since the car has already traveled for 2 hours, it is impossible for it to average 60 mph over the entire trip.
