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