The distance between City D and City E was 990 km apart. A car travelled at an average speed of 92 km/h from City D to City E. At the same time, a bus travelled at an average speed of 73 km/h from City E to City D. 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
= 92 + 73
= 165 km/h
Time taken for the car and the bus to meet
= 990 ÷ 165
= 6 h
Difference in the speed between the car and the bus
= 92 - 73
= 19 km/h
Distance that the car travelled further than the bus
= 6 x 19
= 114 km
Answer(s): 114 km
