Dimensional Analysis!!

Jeff can run one lap in 145 seconds/

How long will it take him to run a mile?

What is his speed in miles per hour?

How long would it take him to run a marathon that pace?

You'll have to tell us how far around one lap is. They are not all the same size.

We had a double indoor track in college. One loop was 1/5 mile and the other was 1/7 mile.
