The distance between City E and City F was 680 km apart. A bus travelled at an average speed of 86 km/h from City E to City F. At the same time, a convertible travelled at an average speed of 84 km/h from City F to City E. 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
= 86 + 84
= 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
= 86 - 84
= 2 km/h
Distance that the bus travelled further than the convertible
= 4 x 2
= 8 km
Answer(s): 8 km
