Question

Bryan, Michael, and Han are painting a house. Working together, they can paint the house in 6 hr. Working alone, Bryan can paint a similar sized house in 15 hr and Han can paint a similar sized house in 18 hr. How many hours would it take Michael to paint a similar sized house working alone? Enter the answer to the nearest tenth.

Answer 1

Answer:

Step-by-step explanation:

11x+90=15x

Answer 2

The computation shows that Michael will take 22.5 hours to paint a similar sized house working

How to compute the value?

Based on the information given, the appropriate equation to use will be:

= 1/15 + 1/18 + 1/Michael = 1/6

Add the two fractions on the left

11/90 + 1/Michael = 1/6

1/Michael = 1/6 - 11/90

Take the reciprocal

Michael = 45/2

Michael= 22.5

Michael will take 22.5 hours.
