Answer:
6.7 days
Step-by-step explanation:
If t is the time the faster roofer takes, then the slower one takes 3t. Their combined rates in roofs per day are ...
1/t + 1/(3t) = 1/5
4/(3t) = 1/5 . . . . . . combine terms
t = 5(4/3) = 20/3 ≈ 6.7 . . . . multiply by 5t
The faster roofer working alone can roof a house in about 6.7 days.
