The distance between City A and City B was 830 km apart. A convertible travelled at an average speed of 87 km/h from City A to City B. At the same time, a car travelled at an average speed of 79 km/h from City B to City A. 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 + 79
= 166 km/h
Time taken for the convertible and the car to meet
= 830 ÷ 166
= 5 h
Difference in the speed between the convertible and the car
= 87 - 79
= 8 km/h
Distance that the convertible travelled further than the car
= 5 x 8
= 40 km
Answer(s): 40 km
