The distance between City A and City B was 860 km apart. A convertible travelled at an average speed of 92 km/h from City A to City B. At the same time, a bus travelled at an average speed of 80 km/h from City B to City A. How much further did the convertible travel than the bus when the convertible met the bus on the way?
Combined speed of the convertible and the bus
= 92 + 80
= 172 km/h
Time taken for the convertible and the bus to meet
= 860 ÷ 172
= 5 h
Difference in the speed between the convertible and the bus
= 92 - 80
= 12 km/h
Distance that the convertible travelled further than the bus
= 5 x 12
= 60 km
Answer(s): 60 km
