The distance between City L and City M was 890 km apart. A car travelled at an average speed of 91 km/h from City L to City M. At the same time, a bus travelled at an average speed of 87 km/h from City M to City L. How much further did the car travel than the bus when the car met the bus on the way?
Combined speed of the car and the bus
= 91 + 87
= 178 km/h
Time taken for the car and the bus to meet
= 890 ÷ 178
= 5 h
Difference in the speed between the car and the bus
= 91 - 87
= 4 km/h
Distance that the car travelled further than the bus
= 5 x 4
= 20 km
Answer(s): 20 km
