The distance between City M and City N was 810 km apart. A convertible travelled at an average speed of 87 km/h from City M to City N. At the same time, a car travelled at an average speed of 75 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
= 87 + 75
= 162 km/h
Time taken for the convertible and the car to meet
= 810 ÷ 162
= 5 h
Difference in the speed between the convertible and the car
= 87 - 75
= 12 km/h
Distance that the convertible travelled further than the car
= 5 x 12
= 60 km
Answer(s): 60 km
