The distance between City D and City E was 680 km apart. A bus travelled at an average speed of 88 km/h from City D to City E. At the same time, a convertible travelled at an average speed of 82 km/h from City E to City D. 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
= 88 + 82
= 170 km/h
Time taken for the bus and the convertible to meet
= 680 ÷ 170
= 4 h
Difference in the speed between the bus and the convertible
= 88 - 82
= 6 km/h
Distance that the bus travelled further than the convertible
= 4 x 6
= 24 km
Answer(s): 24 km
