The stopping distance D of a car after the brakes have been applied varies directly as the square of the speed s. A certain car traveling at 50 mi/h can stop in 240 ft. What is the maximum speed it can be traveling if it needs to stop in 180 ft? Round your answer to one decimal place.
What will be an ideal response?
43.3 mi/h
