Question

Terry's brother can paint a room in 3 hours less than Terry can paint it. Working together they can complete the job in 2 hours. How much time would require Terry to paint the room working alone? Enter just the number no words.

Answer 1

Answer:

6

Step-by-step explanation:

the equation would be 2/(x-3) + 2/x = 1 derived from the work formula of T/A + T/B = 1; T representing total time working together, A/B respectively representing the two different rates of working. In the end Terry would spend 6 hours working alone.
