Question

It takes Henry 2 hours to paint a room. It takes Louisa three hours to paint the same room. If they work together, how long will it take them to paint the room?

Answer 1

Answer:

amount of time it'll take Henry and Louisa = 6/5 hours

Step-by-step explanation:

Number of hours it takes Henry = 2hrs

Henry's one hour work = 1/2

Number of hours it takes Louisa = 3 hrs

Louisa's one hour work = 1/3

Hence Louisa and Henry one hour work = 1/2+1/3 = 5/6

Hence amount of time it'll take Henry and Louisa = 6/5 hours
