Answer:
733 1/3 feet
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
