The distance between City X and City Y was 700 km apart. A car travelled at an average speed of 88 km/h from City X to City Y. At the same time, a bus travelled at an average speed of 87 km/h from City Y to City X. 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
= 88 + 87
= 175 km/h
Time taken for the car and the bus to meet
= 700 ÷ 175
= 4 h
Difference in the speed between the car and the bus
= 88 - 87
= 1 km/h
Distance that the car travelled further than the bus
= 4 x 1
= 4 km
Answer(s): 4 km
