Question 143464: Can you help me with this problem. Five painters can paint 5 houses in 5 days. At that rate, how many days will it take 2 painters to paint 1 house? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Suma can paint a room in ten hours. Bill can paint the same size room in eight hours. How long would it take if they paint the room together.
-------------------
Suma DATA:
Time = 10 hrs/job ; rate = 1/10 job/hr.
--------------------
Bill DATA:
Time = 8 hrs/job ; rate = 1/8 job/hr.
--------------------
Together DATA:
Time = x hrs/job ; rate = 1/x job/hr
=================================================
EQUATION:
rate + rate = together rate
1/10 + 1/8 = 1/x
18/80 = 1/x
x = 80/18
x = 4.44 hours (time to paint the house together)
-----------
