<PRE><B>Question 108464</B>
a machine can fill a 2-liter (L) bottle in 0.5 second (s) and move the next bottle into place in 0.1 s. How many 2-L bottles can be filled by the machine in 2 h? 
-------------
2 hours = 7200 seconds
------------------
Each bottle takes 0.5+0.1 = 0.6 seconds
-----------------
7200/0.6 = 12000 bottles in two hours
