Question

Dahlia hikes 2 14 miles in 12 an hour. At this rate, how long will it take her to walk 18 miles?
4 hours
8 hours
10 hours
12 hours

Answer 1

To find out how long it will take Dahlia to walk 18 miles, we first need to determine her hiking rate in miles per hour.

Dahlia hikes \(2 \frac{1}{4}\) miles (which is \(2.25\) miles) in \(1\) hour.

Now, we can calculate her hiking rate:
- Her rate is \(2.25\) miles/hour.

Next, we want to find the time it will take to walk \(18\) miles at this rate. We can use the formula:

\[
\text{Time} = \frac{\text{Distance}}{\text{Rate}}
\]

Substituting the known values:

\[
\text{Time} = \frac{18 \text{ miles}}{2.25 \text{ miles/hour}}
\]

Now, we perform the calculation:

\[
\text{Time} = \frac{18}{2.25} = 8 \text{ hours}
\]

Thus, it will take Dahlia **8 hours** to walk 18 miles.

The answer is \( \text{8 hours} \).
