Question

The stopping distance , D, of a car after the brakes are applied varies directly as the square of the speed , S, of the car. If a car traveling at a speed of 36 miles per hour can stop in 53 feet, what is the stopping distance of a car traveling at 70 miles per hour? Round your answer to the nearest foot.

Answer 1

Answer: There is no way 200 is the answer. it should be 103.055

Step-by-step explanation: See, 36 miles can stop in 53 feet. We want to know how many feet are there when 70 miles fast. We can write that as 36/53 = 70/x. 36 corresponds to 70 and 53 corresponds to x. Do it and you get 103.055
