The distance between City T and City U was 950 km apart. A convertible travelled at an average speed of 100 km/h from City T to City U. At the same time, a sports car travelled at an average speed of 90 km/h from City U to City T. 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
= 100 + 90
= 190 km/h
Time taken for the convertible and the sports car to meet
= 950 ÷ 190
= 5 h
Difference in the speed between the convertible and the sports car
= 100 - 90
= 10 km/h
Distance that the convertible travelled further than the sports car
= 5 x 10
= 50 km
Answer(s): 50 km
