Problema Solution
Sally can paint a room in 5 hours while Steve takes 4 hours to paint the same room. How long would it take them to paint the room if they worked together?
Answer provided by our tutors
let 'x' represent the time it takes them to paint the room together
1/x = 1/5 + 1/4
solving for 'x' we have x=2.22
0.22 * 60 = 13.2
it would take Sally and Steve approximately 2 hours and 13 minutes to pain the room together
