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.)

Respuesta :

Answer:

It will take 667.239 sec to cover 0.7 miles

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 = [tex]14\times 60+34.56=888.56sec[/tex]

So speed [tex]v=\frac{distance}{time}=\frac{1500}{888.56}=1.688m/sec[/tex]

Now new distance d = 0.7 miles

As 1 miles = 1609 m

So 0.7 miles =[tex]0.7\times 1609=1126.3m[/tex]

So time taken [tex]t=\frac{distance}{velocity}=\frac{1126.3}{1.688}=667.239sec[/tex]
