The distance between City J and City K was 700 km apart. A car travelled at an average speed of 89 km/h from City J to City K. At the same time, a bus travelled at an average speed of 86 km/h from City K to City J. 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
= 89 + 86
= 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
= 89 - 86
= 3 km/h
Distance that the car travelled further than the bus
= 4 x 3
= 12 km
Answer(s): 12 km
