The distance between City J and City K was 900 km apart. A bus travelled at an average speed of 80 km/h from City J to City K. At the same time, a car travelled at an average speed of 70 km/h from City K to City J. How much further did the bus travel than the car when the bus met the car on the way?
Combined speed of the bus and the car
= 80 + 70
= 150 km/h
Time taken for the bus and the car to meet
= 900 ÷ 150
= 6 h
Difference in the speed between the bus and the car
= 80 - 70
= 10 km/h
Distance that the bus travelled further than the car
= 6 x 10
= 60 km
Answer(s): 60 km
