Question

An experienced carpenter can panel a room 3 times faster than an apprentice can. Working together, they can panel the room in 6 hours. How long would it take each one working alone to do the job

Answer 1

experienced carpenter would need 1 and 1/2 hours

apprentice would need 4 1/2 hours

Explanation:

experienced = e

apprentice = 3e

3e + e = 6

4e = 6

e = 6/4 or 3/2

6 - 3/2 = 9/2
