Ahigh school track athlete sprints 100 yards in 15 seconds if there are 5280 feet in a mile and 3600 seconds in an hour determine the runners speed in miles per hour. round to the nearest tenth

3 ft= 1yd

100*3 feet= 100*1yd

300 feet=100yd

Therefore, the athlete ran 300 feet in 15 seconds.

You can simplify it to,

20 ft/sec

Since 300 divided by 15 equals 20 so 20 ft/sec
