If 15 trains pass a point on one track in an hour, what is the headway in minutes for that track?

To determine the headway in minutes when 15 trains pass a point in one hour, you first need to understand what headway means. Headway is the time interval between the arrivals of successive trains at a specific point on a track.

In this case, if 15 trains pass by in one hour, you can calculate the headway by dividing the total time available (in minutes) by the number of trains. Since one hour equals 60 minutes, you use the formula:

Headway = Total time in minutes / Number of trains

Plugging in the values:

Headway = 60 minutes / 15 trains

When you perform the division, you find:

Headway = 4 minutes

This means that there is a 4-minute interval between each train passing that point. Understanding this calculation is crucial for train operations as it helps in scheduling, maintaining safety, and ensuring efficient service.
