Question

A car travels 180 miles in 4 hours. Find the car’s speed in feet per minute. (There are 5,280 ft in 1 mile)

Answer 1

Given :

Distance travelled , d = 180 miles.

Time taken , t = 4 hours.

To Find :

Speed in feet per minutes.

Solution :

Distance in feet is , d = 180×5280 = 950400 feet.

Time taken , t = 4×60 = 240 minutes.

Speed is given by , $s=\dfrac{Distance}{Time \ Taken}$

$S=\dfrac{950400}{240}\ ft/min\\\\S=3960\ ft/min$

Hence, this is the required solution.
