Question

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 swim 0.300 miles (1 mi = 1609 m)? time:

Answer 1

We have relation ,1 min = 60 s. Therefore, 14 min = 14 min x ( 60 s / 1 min ) = 840 s

Therefore, 14 min 34.56 s = 840 s + 34.56 s = 874.56 s

We can calculate swimming rate as, Swimming rate = distance / time.

Therefore, Swimming rate = distance 1 / Time 1 =1500 m / 874.56 s ----------------------------------------->(1)

Convert miles to m

0.300 miles = 0.300 mi x ( 1609 m / 1 mi ) = 482.7 m

We can write , Distance 1 / Time 1 = Distance 2 / Time 2 = 1500 m / 874.56 s ( $\because$ Swimming rate is same)

Therefore, 482.7 m / Time 2 = 1500 m / 874.56 s

Therefore, Time 2 = 482.7 m x 874.56 s / 1500 m = 281.4 s

ANSWER : Time required to swim 0.300 miles = 281.4 s
