Problema Solution

Sally can paint a room in 8 hours while it takes Steve 5 hours to paint the same room. How long would it take them to paint the room they worked together?

Answer provided by our tutors

We can write:

1rm=(1rm/8hrs+1rm/5hrs)t

1=(1/8+1/5)t


Using Algebrator to solve for 't', we get:

t=3.08 hours


This is how long it would take them to paint the room if they worked together.
