The distance between City N and City P was 820 km apart. A car travelled at an average speed of 91 km/h from City N to City P. At the same time, a bus travelled at an average speed of 73 km/h from City P to City N. 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
= 91 + 73
= 164 km/h
Time taken for the car and the bus to meet
= 820 ÷ 164
= 5 h
Difference in the speed between the car and the bus
= 91 - 73
= 18 km/h
Distance that the car travelled further than the bus
= 5 x 18
= 90 km
Answer(s): 90 km
