The stopping distance d of an automobile is directly proportional to the square of its speed s.
On one road, a car requires 75 feet to stop from a speed of 30 miles per hour. How many feet
does the car require to stop from a speed of 48 miles per hour on the same road?

192 feet is the stopping distance at 48 mph.

Step-by-step explanation:

Set up the proportion        

x/75 = 2304/900   cross multiply  to get 900x = 172800

172800 ÷ 900 = 192

x = 192

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
