If you follow a slower driver going five miles per hour below the speed limit for 10 miles, how much will your trip be delayed?

To determine how much your trip will be delayed when following a slower driver going five miles per hour below the speed limit for a distance of ten miles, we calculate the time difference created by the slower speed.

If you are driving at the speed limit and then follow a driver who is going five miles per hour slower, you will cover the same distance in more time. For example, if the speed limit is 55 miles per hour, the slower driver is moving at 50 miles per hour.

To find out how long it takes at each speed:

• At 55 miles per hour, covering 10 miles takes about 10.91 minutes (which is calculated as 10 miles ÷ 55 mph x 60 minutes).

• At 50 miles per hour, covering the same distance takes about 12 minutes (10 miles ÷ 50 mph x 60 minutes).

The difference in time taken is about 1.09 minutes, which rounds to approximately one minute. This shows that the delay caused by following a slower driver for that distance is minimal—just about one minute. Therefore, the answer is indeed about one minute.
