James can paint a room in 4 hours, while Mike can paint the same in 5 hours. Working together, how many hours will take them to paint the room if James only works one hour.
I know that
J = 1/4hr -->if james worked 1/4 of the work
M = 1/5hr -->then Mike worked 3/4 of the work
Destroyer that Mike only needs to work (3/4)*5 = 15/4 = 3 3/4 hours and that is the answer but I do not understand the reasoning behind it. I hope you can help me with this problem
The answer is 3 3/4 hours
