Answer 1

Hey Becky!

The sprinkler covers 1 of 12 parts of the lawn in 1/2 of an hour ( which is 30 minutes).
So to cover all 12 parts of the lawn, we'll need 12 groups of these 30 minutes.

12 * 30 = ? (This will give you your answer in minutes)
Or if you prefer to keep it as a fraction:
12 * (1/2) = ? (This will give you your answer in hours)
