The distance between City A and City B was 860 km apart. A bus travelled at an average speed of 95 km/h from City A to City B. At the same time, a convertible travelled at an average speed of 77 km/h from City B to City A. How much further did the bus travel than the convertible when the bus met the convertible on the way?
Combined speed of the bus and the convertible
= 95 + 77
= 172 km/h
Time taken for the bus and the convertible to meet
= 860 ÷ 172
= 5 h
Difference in the speed between the bus and the convertible
= 95 - 77
= 18 km/h
Distance that the bus travelled further than the convertible
= 5 x 18
= 90 km
Answer(s): 90 km
