A regular bus departed from the bus station at a speed of 54 km / h. After driving 108 km, he made a stop for 20 minutes. After that, he drove another 162 km at the same speed. How long was the bus on the way?

First, we find the period of movement of the bus to the stop.

We divide the distance traveled by the speed of movement.

108/54 = 2 hours.

We find the time that the bus was on the way after a stop.

We divide 162 km by the speed of movement.

162/54 = 3 hours.

We find the total time of the bus in motion.

2 + 3 = 5 hours.

Find the total bus travel time.

To do this, add the stop period to the time in motion.

5 hours + 20 minutes = 5 hours 20 minutes or 5 1/3 hours.

Answer: The bus was on the way for 5 1/3 hours.
