3.68 minutes

9.55 minutes

9.88 minutes

24.15 minutes

The answer is 9.55 minutes

1. Turn 15 km into miles:

1 km = 0.621 mile

15 km = 15 * 0.621 mile = 9.315 miles

So, she ran 9.315 miles for 89 minutes

2. Calculate how many minutes it took Jimena to run 1 mile during the race:

S he ran 9.315 miles for 89 minutes.

She ran 1 mile for x minutes.

9.315 mi : 89 min = 1 mi : x

x = 89 min * 1 mi / 9.315 mi

x = 9.55 min
