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.
