Create a ratio with the information given.
You are given a rate (300ft/10s) and you need to find the time to complete 1 mile = 5280 feet. So here’s the realtionship:
[300 feet/ 10 sec] = [5280 feet/ 'x' sec]
Solving for ‘x’, you get (5280 ft)(10 sec/ 300 ft) = 176 sec = 2.9 min.
Answer is D

Solving for ‘x’, you get (5280 ft)(10 sec/ 300 ft) = 176 sec = 2.9 min.
Answer is D
(5280 ft / mi)/300 ft = 17.6 * 10 secs to run a mile
176 s to run a mile
176/60 = 3 min to run a mile
(D) is the answer
