The distance between City Q and City R was 870 km apart. A bus travelled at an average speed of 99 km/h from City Q to City R. At the same time, a car travelled at an average speed of 75 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
= 99 + 75
= 174 km/h
Time taken for the bus and the car to meet
= 870 ÷ 174
= 5 h
Difference in the speed between the bus and the car
= 99 - 75
= 24 km/h
Distance that the bus travelled further than the car
= 5 x 24
= 120 km
Answer(s): 120 km
