The distance between City V and City W was 640 km apart. A bus travelled at an average speed of 87 km/h from City V to City W. At the same time, a car travelled at an average speed of 73 km/h from City W to City V. How much further did the bus travel than the car when the bus met the car on the way?
Combined speed of the bus and the car
= 87 + 73
= 160 km/h
Time taken for the bus and the car to meet
= 640 ÷ 160
= 4 h
Difference in the speed between the bus and the car
= 87 - 73
= 14 km/h
Distance that the bus travelled further than the car
= 4 x 14
= 56 km
Answer(s): 56 km
