The distance between City V and City W was 720 km apart. A car travelled at an average speed of 100 km/h from City V to City W. At the same time, a bus travelled at an average speed of 80 km/h from City W to City V. 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
= 100 + 80
= 180 km/h
Time taken for the car and the bus to meet
= 720 ÷ 180
= 4 h
Difference in the speed between the car and the bus
= 100 - 80
= 20 km/h
Distance that the car travelled further than the bus
= 4 x 20
= 80 km
Answer(s): 80 km
