Question: 1 / 400

If you are traveling at 55 mph, what is the braking distance?

100 feet

The correct braking distance at 55 mph is typically around 120 feet, depending on various factors such as vehicle type, road conditions, and tire conditions. Braking distance is influenced by the speed at which a vehicle is traveling. At higher speeds, the vehicle will naturally require more distance to come to a complete stop due to the increased kinetic energy.

Considering this, the actual stopping distance for a vehicle at 55 mph would more closely align with the response indicating 120 feet. Other choices, like 100 feet, would be too short for the average stopping distance at that speed, while 150 feet or 170 feet would be more applicable in specific conditions or with heavier vehicles or those with less effective braking systems. It's essential for drivers to be aware of their braking distances and adjust their speed accordingly in various driving conditions.
