The distance between City M and City N was 820 km apart. A convertible travelled at an average speed of 83 km/h from City M to City N. At the same time, a car travelled at an average speed of 81 km/h from City N to City M. 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
= 83 + 81
= 164 km/h
Time taken for the convertible and the car to meet
= 820 ÷ 164
= 5 h
Difference in the speed between the convertible and the car
= 83 - 81
= 2 km/h
Distance that the convertible travelled further than the car
= 5 x 2
= 10 km
Answer(s): 10 km
