John ran the 100 m dash with a time of 9.88 sec. If this pace could be maintained for an entire 26 mi marathon, what would his time be?

approximately 72.35 minutes

Step-by-step explanation:

there are 1609.344 meters in a mile

john ran 100 meter - which would be 16.09 per mile

9.88 seconds x 16.9 = 166.97 seconds per mile

166.97 seconds x 26 miles = 4341.22 seconds

4341.22 seconds / 60 = 72.35 minutes
