Answer:
124.67 feet per second
Explanation:
First: multiply the feet per mile by the amount of miles that the car is going in order to get the feet per hour
5280 x 85 = 448,800
Second: divide the answer from the first step by 60 in order to get the number of feet per minute
448,800 ÷ 60 = 7480
Third: divide the answer from the second step by 60 in order to get the number of feet per second
7480 ÷ 60 = 124.67
