Question

The coach recorded how fast her runners ran 1 mile. Eric ran a mile in 10.84 minutes, Kay ran a mile in 12.79 minutes, and Rosie ran a mile in 9.58 minutes. How many more minutes did Eric run than Rosie?

Answer 1

1.26 minutes

Explanation:

The runners all ran the same distance of 1 mile.

Eric's time to run 1 mile = 10.84 minutes

Kay's time to run 1 mile = 12.79 minutes

Rosie's time to run 1 mile = 9.58 minutes

This implies that Rosie is the fastest runner among the three.

The difference between Eric and Rosie's time = Eric's time - Rosie's time

= 10.84 - 9.58

= 1.26

The difference between Eric and Rosie's time shows the minutes Eric ran more than Rosie. Therefore, Eric ran 1.26 minutes more than Rosie.
