The length (in feet) of skid marks of a car's tires (when the brakes are applied) is directly proportional to the square of the speed (in miles per hour) of the car. The length of the skid marks is 100 ft when the speed is 50 mi/h. Find the length of the skid marks when the speed is 60 mi/h.
What will be an ideal response?
