The distance between City G and City H was 770 km apart. A bus travelled at an average speed of 81 km/h from City G to City H. At the same time, a convertible travelled at an average speed of 73 km/h from City H to City G. 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
= 81 + 73
= 154 km/h
Time taken for the bus and the convertible to meet
= 770 ÷ 154
= 5 h
Difference in the speed between the bus and the convertible
= 81 - 73
= 8 km/h
Distance that the bus travelled further than the convertible
= 5 x 8
= 40 km
Answer(s): 40 km
