Question

The men's world record for swimming 1500.0 m in a long course pool (as of 2007) is 14 min 34.56s. At this rate, how many seconds would it take to swim 0.350 miles? (1 mi=1609)

Answer 1

1 mile= 1609 m
0.350 miles = 0.350 · 1609 = 563.15 m
t = 14 min 34.56 s = 874.56 s
velocity: 1500 m: 874.25 s = 1.715 m/s
t 1 = 563.15 : 1.715 m/s = 328.37 s = 5 min 28.37 s.
At this rate it would take 328.37 seconds to swim 0.350 miles.
