Question

Leslie is trying to figure out how long her 25 mile hike will take. If every group of 5 miles takes 30 minutes, how many hours will her will her whole teip take?

Answer 1

We know that each group of 5 miles takes 30 minutes, we need to find how many groups she hikes:

$\frac{25}{5}=5$

Then she hikes 5 groups of 5 miles.

Now we multiply this number of groups for the time it takes:

$5\cdot30=150$

Then it takes 150 minutes for the whole hike. Finally we divide this by 60 minutes (each hour is equal to 60 minutes):

$\frac{150}{60}=2.5$

Therefore it takes 2.5 hours to make the hike
