Little Texas Drilling Company has three wells, each producing oil at a constant rate. Well A produces one barrel every two minutes. Well B produces one barrel every three minutes. Well C produces one barrel every four minutes. How many hours does it take Little Texas Drilling Company to produce 115 barrels of oil? Choose the correct choice from the following options:
A) 2 B) 3 C) 4 D) 18 E) 180
Well A produces 1/2 a barrel per minute.   Wells B and C produce 1/3 + 1/4 = 7/12 (a little more than half) a barrel per minute.   So all three wells combined produce a little more than 1 barrel per minute.   So for 115 barrels they will take a bit less than 115 mins which will be more than 1 hrs but less than 2 hrs.   2nswer (2)
