The distance between City M and City N was 760 km apart. A car travelled at an average speed of 100 km/h from City M to City N. At the same time, a bus travelled at an average speed of 90 km/h from City N to City M. 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 + 90
= 190 km/h
Time taken for the car and the bus to meet
= 760 ÷ 190
= 4 h
Difference in the speed between the car and the bus
= 100 - 90
= 10 km/h
Distance that the car travelled further than the bus
= 4 x 10
= 40 km
Answer(s): 40 km
