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

Hope this helps, have a good day. c;

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

the answer is 21%.
