The men's world record for swimming 1500.0 m in a long course pool (as of 2007) is 14 min 34.56 s. At this rate, how many seconds would it take to swim0.650miles (1 mi = 1609 m) ?

10.16 minutes

Explanation:

14 min 34.56 s = 14*60 + 34.56 = 874.56 seconds

The speed of record swimming is distance over time

v = 1500 / 874.56 = 1.715 m/s

0.65 miles = 0.65 * 1609 = 1045.85 m

The time it takes to swim 0.65 miles (1045.85 m) at the rate of 1.715 m/s is

t = s/v = 1045.85 / 1.715 = 609.77 s or 609.77 / 60 = 10.16 minutes
