The distance between City V and City W was 870 km apart. A convertible travelled at an average speed of 90 km/h from City V to City W. At the same time, a car travelled at an average speed of 84 km/h from City W to City V. 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
= 90 + 84
= 174 km/h
Time taken for the convertible and the car to meet
= 870 ÷ 174
= 5 h
Difference in the speed between the convertible and the car
= 90 - 84
= 6 km/h
Distance that the convertible travelled further than the car
= 5 x 6
= 30 km
Answer(s): 30 km
