Question
A train travels from City A to City B at a speed of 60
km/h and then from City B to City C at a speed of 80 km/h. The distance between City A and City B is 240 km, and the distance between City B and City C is 320 km. What is the average speed of the train for the entire trip?Solution
The formula for average speed is: Average speed = Total distance / Total time. Total distance = 240 km + 320 km = 560 km. Time taken from City A to City B = 240 / 60 = 4 hours. Time taken from City B to City C = 320 / 80 = 4 hours. Total time = 4 + 4 = 8 hours. Average speed = 560 / 8 = 70 km/h.
