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 0.150 miles?

140 s. It would take 140 s to swim 0.150 mi.

Step 1. Convert the time to seconds

Time = 14 min * (60 s/1 min) + 34.56 s = 840 s + 34.56 s = 874.56 s

Step 2. Convert miles to metres

Distance = 0.150 mi * (1609.3 m/1 mi) = 241.4 m

Step 3. Calculate the time to swim 241.4 m

Time = 241.4 m * (874.56 s/1500 m) = 140 s

(As of 2012, the men's freestyle record for 1500 m was 14:31.02.)
