To find the stopping distance of a car traveling 75 mph, we first need to calculate the stopping distance at 45 mph per foot and then use that information to determine the stopping distance at 75 mph.
Since we know that the stopping distance at 45 mph is 121.5 ft, we can set up a proportion to find the stopping distance at 75 mph:
45 mph = 121.5 ft
75 mph = x ft
Cross multiply to solve for x:
45 * x = 75 * 121.5
45x = 9127.5
x = 9127.5 / 45
x = 202.72 ft
Therefore, the stopping distance of a car traveling 75 mph is approximately 202.72 ft.
If a car traveling 45 mph has a stopping distance of 121.5 ft, find the stopping distance of a car that is traveling 75 mph.
