Answer:

733 1/3 feet

$(733.\bar{3} \: ft)$

Explanation:

There are 60 seconds in a minute and 60 minutes in an hour.

S = d/t →

S × t = d/t × t →

St = d →

D = st.

Because the speed is in mph, the time is relative to hours.

This means that t = 1 at one hour.

To find the distance, we need to know how many seconds are in an hour.

Knowing that 60 seconds are in a minute and 60 minutes are in an hour.

60 × 60 = 3600.

3600 seconds / hour.

Given the speed is 100 miles / hour,

and that the time traveled is 5 seconds.

D = s × t = D = (miles per hour) × (seconds / 3600) =

100 × 5 / 3600 = 500 / 3600 =

10 / 72 miles.

There are 5280 feet in a mile, so

5280 × 10 / 72 = 52800 / 72 =

26400 / 36 = 13200 / 18 =

6600 / 9 = 2200 / 3 = 733 1/3
