What is the braking distance for a vehicle moving at 50 mph?

100 ft
125 ft
150 ft
175 ft

The correct answer is: 125 ft

At 50 mph, the average braking distance for a vehicle is around 125 ft. At this speed, it takes a vehicle approximately 4.5 seconds to come to a complete stop. Option A of 100 ft is incorrect because it is too short an estimate. Option C of 150 ft is also incorrect because it is too long an estimate. Option D of 175 ft is also incorrect because it is an even longer estimate. The average braking distance can vary based on factors such as the type and condition of the road, weather conditions, and the vehicle's weight and brake system. However, 125 ft is a good estimate for a vehicle's braking distance at 50 mph on a dry, level surface.
