Problema Solution
Two painters, Jane and Jesse, working together paint a certain room in 3 hours. If it takes Jesse, working alone, 8 hours to paint the room, how long would it take Jane to paint the same room all by herself?
Answer provided by our tutors
lets say that Jane needs x hours to paint the same room by herself
Jessie's rate when working alone is 1 room in 8 hours: 1/8 rooms/hour
if the work together they paint the room in 3 hours
1/x + 1/8 = 1/3
by solving the equation we find
x = 4.8 hours
