Question

Two bricklayers San and Joe are working on your house San can complete the work in 5 hours Joe can complete the work in 3 hours

Answer 1

guessing this is a combined work problem??? You forgot to post the question. I can solve for the time it takes them to complete the house together..

1/3 + 1/5 = 1/t
5/15 + 3/15 = 1/t
8/15 = 1/t
15/8 = t
1.875 hrs
