From two cities, the distance between which is 846 km, two trains left at the same time to meet each other. One walked at a speed of 85 km / h, the other at a speed of 60 km / h. What is the distance between trains in 3 hours?

Let’s calculate how far the first train will travel in 3 hours:
1) 85 km / h * 3 h = 255 km – the first train will pass in 3 hours.
Let’s determine how far the second train will travel in 3 hours:
2) 60 km / h * 3 h = 180 km – the second train will pass in 3 hours.
Let’s find out how far two trains will travel together in 3 hours:
3) 255 + 180 = 435 km – two trains will pass in 3 hours.
Let’s calculate the distance between trains in 3 hours:
4) 846 – 435 = 411 km – will be between trains in 3 hours.
Answer: 411 km.
