Solution is above the model.
Instead of finding out how long they take together to paint one unit, you calculate how long they take together to paint two units instead. But if you want to do the former (find out how much they take to paint one unit), you must divide 35 (as derived from 15+20) by 2, then times ten (since ten units left to paint). The answer will still be the same, 175min :) I hope I helped :)
