The distance between City Q and City R was 850 km apart. A convertible travelled at an average speed of 89 km/h from City Q to City R. At the same time, a car travelled at an average speed of 81 km/h from City R to City Q. How much further did the convertible travel than the car when the convertible met the car on the way?
Combined speed of the convertible and the car
= 89 + 81
= 170 km/h
Time taken for the convertible and the car to meet
= 850 ÷ 170
= 5 h
Difference in the speed between the convertible and the car
= 89 - 81
= 8 km/h
Distance that the convertible travelled further than the car
= 5 x 8
= 40 km
Answer(s): 40 km
