Question - Understanding Bus Timings and Schedules

Let the time taken for each bus to complete a single trip be \( t \) minutes.

Therefore, if there are three buses, they will take \( 3t \) minutes to return.

If they all leave together and travel for the same duration, they will be back at the station at \( 3t \) minutes.

To find out how many trips each bus would have made by this time:

Each bus will have made \( \frac{3t}{t} = 3 \) trips.
