Question 1155429: A state patrol officer saw a car start from rest at a highway on-ramp. She radioed ahead to another officer 28 mi along the highway. When the car reached the location of the second officer 22 min later, it was clocked going 60 mi/hr. The driver of the car was given a ticket for exceeding the 60 mi/hr speed limit. Why can the officer conclude that the driver exceeded the speed limit?

The key to solve the problem is understanding that the speed of  60 miles per hour is the same as 1 mile per minute.


Would the driver move under the speed limit, then he (or she) could cover not more than  22 miles in 22 minutes.


But since the driver covered more than that in 22 minutes, he (or she) really exceeded the speed limit of 60 mph.

Solved and explained in all details.

By the way, one important conclusion and a practical lesson to learn from my solution is THIS

    For the traffic police officers, it is not necessary to see firsthand/personally as the driver exceeds the speed limit.

    If they are armed by this technique and this LOGIC (!), they can detect and to prove the fact of exceeding the speed "remotely".
