Question 354673: Hello,
One pipe can fill a tank in 2 h, a second pipe can fill the tank in 4 h, and a third pipe can fill the tank in 5 h. How long will it take to fill the tank with all three pipes working?
Okay, so this is how I thought it might look like:
1/2 + 1/4 + 1/5 = 3
Then I multiplied all of them by the LCM 20. However, when I was done my answer came out to be 60/19 and that just does not seem right to me. Hope you can help me with this problem! Thank you for your time = ) Answer by scott8148(6628) (Show Source):
