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?

Answer 1

Total shift-plus-fill time is 0.6 s. Divide 120*60 = 7200 s by 0.6 s for the answer.

Answer 2

There are 60 min in 1 hour.
There are 60 seconds in 1 min.
How many 0.6 seconds are there in that many total seconds?
