Question 1013765: Jose paints a wall in 5 days. If Jose and Alfred works together fot at most 2 days, what must be the minimum rate of Alfred to complete the job ? Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Call Alfred's solo time t. The set up is like this
2/5 + 2/t = 1
Multiply by 5t and get
2t + 10 = 5t
10 = 3t
t = 10/3 days
