Owl can clean piglets house in 25 minutes. eeyore can clean piglets house in 40 minutes. how long will it take owl and eeyore to do the job if they work together?

Respuesta :

barnuts

Let us say that the task of cleaning the house is equal to 1 job. Therefore the rates are:

 

rate of Owl = 1 job / 25 minutes

rate of eeyore = 1 job / 40 minutes

 

So working together, the time is:

(1 / 25) + (1 / 40) = 1 / t

0.065 = 1 / t

t = 15.38 minutes

 

So it takes about 15.38 minutes working together.
