BUBBA AND RUSTY
SPRING A LEAK
After devouring a couple of double cheeseburgers at Joey's Meat Cutter's Inn, Bubba and Rusty decided to go fishing in Bubba's rusty boat. Two hours passed without a single bite before both Rusty and Bubba fell into a sound sleep. Upon awakening, they discovered that Bubba's boat had sprung a leak. Water was coming in at a uniform rate and some had already accumulated. At this point, 12 men of equal skill can pump the boat dry in 3 hours, while 5 men require 10 hours. How many men are needed to pump it dry in 2 hours?
