Math Question: If you have an oval track, one mile around, and a car averages 30mph on the first lap,....?

Question

how fast does the car need to go on the second lap to average 60mph over both laps??? Hint: It's not 90mph.

Answer 1

To average 30mph for 1 mile (one lap) takes 2 minutes.

To average 60 mph for 2 miles (two laps) takes 2 minutes.

You need to go infinite speed on the second lap to make up the average speed.

Answer 2

3600mph

at this speed you will average very very close to sixty miles an hour as it will only take 1 second to cover the second lap. Resulting in a time of 1 mile at 30mph taking 2 mins and 1 mile at 3600mph taking 1 second. The total time of 2:01 equates to an average speed of just under 60mph

Answer 3

120mph
