The distance between City S and City T was 770 km apart. A convertible travelled at an average speed of 80 km/h from City S to City T. At the same time, a bus travelled at an average speed of 74 km/h from City T to City S. How much further did the convertible travel than the bus when the convertible met the bus on the way?
Combined speed of the convertible and the bus
= 80 + 74
= 154 km/h
Time taken for the convertible and the bus to meet
= 770 ÷ 154
= 5 h
Difference in the speed between the convertible and the bus
= 80 - 74
= 6 km/h
Distance that the convertible travelled further than the bus
= 5 x 6
= 30 km
Answer(s): 30 km
