The distance between City J and City K was 660 km apart. A bus travelled at an average speed of 83 km/h from City J to City K. At the same time, a convertible travelled at an average speed of 82 km/h from City K to City J. 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
= 83 + 82
= 165 km/h
Time taken for the bus and the convertible to meet
= 660 ÷ 165
= 4 h
Difference in the speed between the bus and the convertible
= 83 - 82
= 1 km/h
Distance that the bus travelled further than the convertible
= 4 x 1
= 4 km
Answer(s): 4 km
