The distance between City Q and City R was 760 km apart. A bus travelled at an average speed of 81 km/h from City Q to City R. At the same time, a car travelled at an average speed of 71 km/h from City R to City Q. How much further did the bus travel than the car when the bus met the car on the way?
Combined speed of the bus and the car
= 81 + 71
= 152 km/h
Time taken for the bus and the car to meet
= 760 ÷ 152
= 5 h
Difference in the speed between the bus and the car
= 81 - 71
= 10 km/h
Distance that the bus travelled further than the car
= 5 x 10
= 50 km
Answer(s): 50 km
