Project Full Stop Ahead
Math 2 Unit 1
By: Bailey Williams
Why do you think the estimates of speed do not double in length? Based on these results, what conclusions can you make about safe distances between cars?
- When you are driving, you need to have a safe following distance between your car and the car in front of you. The safe following distance all depends on your speed and the amount of time it would take you to stop.
Suppose you are driving on a dry road with 150 ft (about 10 car lengths) between you and the car in front of you. Use the formula from activity one to find the maximum speed you should be traveling in order to leave a safe stopping distance.
- The maximum speed for a safe stopping distance is 64-65 mph.
