<u>Answer: </u>
In 3 hour 15 minutes Dennis will walk 9.2072 miles.
<u>Solution: </u>
It is given that Dennis can walk 2.833 miles each hour. We have to find how far will he walk in 3 hours 15 minutes.
We first convert 15 minutes in hour. To convert 15 minutes in hour we divide 15 by 60.
Therefore 3 hours 15 minutes can be written as
