The train moved at a speed of 110 km / h for two hours, and then traveled another 180 km at a speed of 90 km / h. What is the average speed of the train along the way?
To find the average speed of a train, you need to divide the entire distance by the entire time.
Distance = 110 x 2 + 180 = 400 km.
All the time = 4 hours.
Then the average speed is 400 ÷ 4 = 100 km / h
Answer: 100 km / h
