A 10 kilometer race is about 6.2 miles long. Teresa completes the race in 58 minutes. What is her average time per mile? Give your answer in minutes and seconds.

Answer 1

For the 10 K race in 58 minutes
the runner would take 5.8 minutes per km
or
5 minutes and 48 seconds to run 1 km

The equivalent race of 6.2 miles
would have a time of 58/6.2 minutes per mile
or 9.3548.. minutes per mile
= 9 minutes, 21 seconds

(A real runner doing a 10 K race would not think of miles, he/she would be familiar with the metric system and know not to convert.)
