How do you calculate Running Time?

The correct method to calculate Running Time is by taking the length of the route and dividing it by the speed (in miles per hour). This approach gives you the time taken to travel that distance based on the given speed. In this case, running time is expressed in hours.

To correctly compute running time using the formula, if you consider the length in miles and the speed in miles per hour, the formula is:

Running Time (hours) = Length (miles) / Speed (miles per hour).

This means that the value of "Length" needs to be divided by "Miles per hour" to arrive at the time in hours. The option that correctly reflects this calculation is derived from that logic.

The approach of multiplying the length by 60 and dividing by the speed is incorrect because it would create a unit mismatch and distort the actual time calculated, deviating from the fundamental relationship between distance, speed, and time. This is critical for understanding how running time is properly derived in transit operations.
