Keeping in mind the average reaction time, a motorist will travel 11 feet for each __________ of speed before hitting the brake.15 mph20 mph5 mph10 mph

The average reaction time for a motorist is about 1.5 seconds. This means that a motorist will travel a certain distance during this time before they can physically hit the brakes. The distance traveled depends on the speed of the vehicle.

The formula to calculate this is: Distance = Speed x Time

Given that the time is 1.5 seconds, we can calculate the distance for each speed:

1. For 15 mph: Convert the speed to feet per second: 15 mph = 22 feet/second Distance = 22 feet/second x 1.5 seconds = 33 feet

2. For 20 mph: Convert the speed to feet per second: 20 mph = 29.33 feet/second Distance = 29.33 feet/second x 1.5 seconds = 44 feet

3. For 5 mph: Convert the speed to feet per second: 5 mph = 7.33 feet/second Distance = 7.33 feet/second x 1.5 seconds = 11 feet

4. For 10 mph: Convert the speed to feet per second: 10 mph = 14.67 feet/second Distance = 14.67 feet/second x 1.5 seconds = 22 feet

So, a motorist will travel 11 feet for each 5 mph of speed before hitting the brake.
