- The bus travels at 60 km/h without any stops.

- When including stops, its average speed drops to 51 km/h.

- This implies the bus spends some time stationary every hour.

- The difference between 60 km and 51 km is 9 km.

- This means the bus doesn't travel 9 km each hour due to stoppages.

- The time taken to travel these 9 km is the stoppage time.

- Speed = Distance/Time. So, Time = Distance/Speed.

- The stoppage time = 9 km / 60 km/h = 0.15 hours.

- To convert 0.15 hours to minutes: 0.15 * 60 = 9 minutes.

- Option:1, 9 minutes, is correct.
