First of all, you need to find out how many tons of coal one train will carry:

1) 10 wagons * 3 tons = 30 tons – fits into 1 train.

Now we find out the required number of trains, if we divide the entire amount of coal by 30 tons:

2) 600 tons / 30 tons = 20 trains.

Bottom line: you need twenty trains.
