Interpretation : The passenger who travelling in a car at a given speed, then the number feet travelled in one second should be calculated.
Concept Introduction :
The conversion factor is a numeric ratio which used to prove a measurement in one unit as another unit which is always equal to one.

Answer to Problem 75A
The passenger covers
Explanation of Solution
Given information :
The speed of the car is,
The given speed is 55 miles per hour which means that, the passenger travels 55 miles in 3600 seconds. While 1 mile contains 5280 feet. Therefore, the passenger covers
The passengers cover distance in one feet is,
The passenger covers
