Problema Solution
Kimberly runs 60 feet in 10 seconds. How long will it take to run a mile?
Answer provided by our tutors
d = 1 mile = 5280 ft
the rate of Kimberly is v = 60/10 = 6 ft/s
since speed = distance/time => time = distance/speed
t = d/v
t = 5280/6
t = 880 s
t = 14 min 40 s
It will take her 14 min and 40 seconds to run a mile.
