The car was moving approximately at a speed of 37.74 miles per hour.
Step-by-step explanation:
We are given the following in the question:
The stopping distance of a car is given by

where d is the stopping distance in feet and r is speed of the car in miles per hour.
The stopping distance is 75 feet, we have to find the speed of the car,
Putting d = 75 in the equation, we get,

Thus, the car was moving approximately at a speed of 37.74 miles per hour.
X is the Scale factor so 18/6=X
X=3
Another way to check. the work is 6 x 3 = 18
