The distance between City W and City X was 860 km apart. A convertible travelled at an average speed of 98 km/h from City W to City X. At the same time, a sports car travelled at an average speed of 74 km/h from City X to City W. How much further did the convertible travel than the sports car when the convertible met the sports car on the way?
Combined speed of the convertible and the sports car
= 98 + 74
= 172 km/h
Time taken for the convertible and the sports car to meet
= 860 ÷ 172
= 5 h
Difference in the speed between the convertible and the sports car
= 98 - 74
= 24 km/h
Distance that the convertible travelled further than the sports car
= 5 x 24
= 120 km
Answer(s): 120 km
