Click on ONE answer only. Compared to driving at 20 mph, about how much longer will it take for you to stop at 60 mph? about six times as far about nine times as far about twice as far

## Step 1The problem is about the relationship between speed and stopping distance in physics. The stopping distance is the distance a vehicle travels from the time the driver applies the brakes until the vehicle comes to a complete stop. This distance is influenced by the speed of the vehicle and the reaction time of the driver.## Step 2The stopping distance is generally proportional to the square of the speed. This means that if the speed is doubled, the stopping distance will increase by a factor of four. ## Step 3In this problem, the speed is increased from 20 mph to 60 mph, which is a threefold increase. ## Step 4Since the stopping distance is proportional to the square of the speed, the stopping distance will increase by a factor of .
