Find the average speed of a freight train if on the first section it moved at a speed of 60 km / h on the second 90 km / h on the third 110 km / h and on the fourth 100 km / h.
To find the average speed of a freight train, we need to add all the speeds in different sections and divide by the number of sections.
We have: 60 + 90 + 110 + 100 = 360 (km / year) – this is the sum of all speeds.
Divide into 4 sections, we have: 360/4 = 90 (km / year) – this is the average speed of a freight train.
Answer: 90 km / year.
