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 3 hours and 30 minutes?
Each hour is 60 minutes, so convert the second value to minutes.
3*60+30=210 (for converting to minutes)
If she can eat 1 popsicle per 15 minutes, divide 210 by 15. This comes out to 14, so she can eat 14 popsicles in 3 hours and 30 minutes.
