The distance between City Y and City Z was 830 km apart. A lorry travelled at an average speed of 96 km/h from City Y to City Z. At the same time, a car travelled at an average speed of 70 km/h from City Z to City Y. How much further did the lorry travel than the car when the lorry met the car on the way?
Combined speed of the lorry and the car
= 96 + 70
= 166 km/h
Time taken for the lorry and the car to meet
= 830 ÷ 166
= 5 h
Difference in the speed between the lorry and the car
= 96 - 70
= 26 km/h
Distance that the lorry travelled further than the car
= 5 x 26
= 130 km
Answer(s): 130 km
