To determine how long the students are on the bus, you calculate the time difference between when they board and when they arrive at school. They board the bus at 7:45 a.m. and arrive at 8:20 a.m.

To find the duration, subtract the boarding time from the arrival time. Here’s the breakdown:

- From 7:45 a.m. to 8:00 a.m. is 15 minutes.

- From 8:00 a.m. to 8:20 a.m. is an additional 20 minutes.

Adding these segments together results in 15 minutes plus 20 minutes, giving a total of 35 minutes on the bus.

This process shows how the correct answer reflects the actual calculation of time spent traveling. Understanding how to calculate time intervals is essential for solving similar problems involving time management or scheduling in an educational setting.
