The distance between City J and City K was 840 km apart. A convertible travelled at an average speed of 97 km/h from City J to City K. At the same time, a car travelled at an average speed of 71 km/h from City K to City J. 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
= 97 + 71
= 168 km/h
Time taken for the convertible and the car to meet
= 840 ÷ 168
= 5 h
Difference in the speed between the convertible and the car
= 97 - 71
= 26 km/h
Distance that the convertible travelled further than the car
= 5 x 26
= 130 km
Answer(s): 130 km
