Birdhouse 12941

Michal would make a birdhouse in three hours, and Richard would make it in two hours. If they work together, how many hours will it take them to complete it? How much percent more time compared to the time of working together would Michal make the booth by himself?

Correct answer:

s =  1.2 h
p =  150 %

Step-by-step explanation:


s·(1/3+1/2)=1

5s = 6


s = 6/5 = 1.2

s = 6/5 = 1.2

Our simple equation calculator calculates it.
p=100 s3s=100 1.231.2=150%
