On a hot day, Megan likes to eat a Popsicle every 15 minutes. Assuming she keeps up that rate of consumption, how many Popsicles can Megan finish in 4 hours and 30 minutes?
To solve this problem, I need to convert the units of time to the same scale. 4 hours and 30 minutes is equivalent to 270 minutes, since there are 60 minutes in an hour. Now I can divide 270 minutes by 15 minutes per Popsicle to get the number of Popsicles. 270 divided by 15 is 18, so Megan can eat 18 Popsicles in 4 hours and 30 minutes.
