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 0.700 miles (1 mi = 1609 m)? (1 mi = 1609 m.)

Answer 1

It will take 667.239 sec to cover 0.7 miles

Step-by-step explanation:

We have given the men's world record in swimming is 1500 m in 1 min 34.56 sec

So distance d = 1500 m

Time t = 14 min 34.56 sec

As 1 minute = 60 sec

So time t =
`14* 60+34.56=888.56sec`

So speed
`v=(distance)/(time)=(1500)/(888.56)=1.688m/sec`

Now new distance d = 0.7 miles

As 1 miles = 1609 m

So 0.7 miles =
`0.7* 1609=1126.3m`

So time taken
`t=(distance)/(velocity)=(1126.3)/(1.688)=667.239sec`
