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 265 barrels of oil?
Choose the correct choice from the following:
A) 2  B) 3  C) 4  D) 5  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 265 barrels they will take a bit less than 265 mins which will be more than 4 hrs but less than 5 hrs.   Answer (5)
