What is the stopping distance for 40mph?

Answer: C — 118 ft

The stopping distance at 40mph is influenced by several factors such as road conditions, vehicle weight, and tire condition. According to research, the average stopping distance for a passenger car traveling at 40mph is about 118 feet. Option A, 98 feet, may seem like a viable answer, but it is on the lower end and does not account for potential variables that may require a longer stopping distance. Options B and D, 108 ft and 128 ft respectively, are also possible stopping distances, but they are not the most accurate and fall outside of the average range. Therefore, option C, 118 feet, is the most appropriate and reliable answer for the stopping distance at 40mph.
