In a bottling company, a machine can fill a 2-liter bottle in 0.5 seconds and move the next bottle into place in 0.1 seconds. How many 2-liter bottles can be filled by the machine in 2 hours?
First -- let's find the number of seconds in 2 hours.
60 * 60 = 3600 seconds in 1 hour
7200 seconds in 2 hours
Now divide: 7200 / 0.6 = 12,000 bottles
