Question

9. In 2001, Alan Webb broke Jim Ryun's 36-vear-old high school mile record by running I mile
in 3 minutes 53.43 seconds. How fast was this in feet per second?

Answer 1

Answer:

$22.62\frac{ft}{sec}$

Step-by-step explanation:

we know that

$1\ mi=5,280\ ft$

To convert miles to feet multiply by 5,280

$1\ min=60\ sec$

To convert minutes to seconds multiply by 60

we have

$3\ min\ 53.43\ sec=3(60)+53.43=233.43\ sec$

To find out the speed in feet per second, divide the distance in feet by the time in seconds

so

$\frac{5,280}{233.43}=22.62\frac{ft}{sec}$
