The distance between City Y and City Z was 850 km apart. A sports car travelled at an average speed of 98 km/h from City Y to City Z. At the same time, a bus travelled at an average speed of 72 km/h from City Z to City Y. How much further did the sports car travel than the bus when the sports car met the bus on the way?
Combined speed of the sports car and the bus
= 98 + 72
= 170 km/h
Time taken for the sports car and the bus to meet
= 850 ÷ 170
= 5 h
Difference in the speed between the sports car and the bus
= 98 - 72
= 26 km/h
Distance that the sports car travelled further than the bus
= 5 x 26
= 130 km
Answer(s): 130 km
