Question

Alex, Barry, Charles, David, and Eric paint houses for a living. Alone, Alex can paint an entire house in 24 hours, Barry in 26 hours, Charles in 20 hours, David in 21 hours and Eric in 27 hours. If they work together, approximately how long will it take them to paint 3 houses, rounded to the nearest hour?

Answer 1

It would take 14 hours for all of them to paint the three houses.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

Let t represent the time it would take them working together, hence:

(1/24 + 1/26 + 1/20 + 1/21 + 1/27)t = 3

t = 14 hours

It would take 14 hours for all of them to paint the three houses.
