Question 853241: The distance it takes to stop a car varies directly as the square of speed of the car. If it takes 112 feet for a car traveling at 40 miles per hour to stop, what distance is required for a speed of 62 miles per hour> Answer by JulietG(1812) (Show Source):
You can put this solution on YOUR website! The square is the key.
40 squared = 1600
1600 / 112 = 14.286 is the ratio
62 squared = 3844
Divide that by 14.286 to get 269 feet
