Dennis can walk 2.833 miles each hour . About how far can he walk in 3 hours and 15 minutes
vovikov84 [41]

<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.

\text { Thus } 15 \text { minutes }=\frac{15}{60} \text { hour }=\frac{1}{4} \text { hours. }

Therefore 3 hours 15 minutes can be written as 3+\frac{1}{4} \text { hours }=\frac{13}{4} \text { hours }

Now,

In 1 hour dennis can walk 2.833 miles

\ln \frac{13}{4} \text { hour dennis will walk } 2.833 \times \frac{13}{4} \text { hours }=9.2072 \text { miles }

Thus in 3 hour 15 minutes Dennis will walk 9.2072 miles.
