Answer 1

To find how many miles per hour Arianna rides her bicycle, we can use the formula:

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

We can use any of the pairs from the table, but let's use the first one for simplicity:

- Distance: 42 miles
- Time: 3 hours

Now we plug the values into the formula:

\[
\text{Speed} = \frac{42 \text{ miles}}{3 \text{ hours}} = 14 \text{ miles per hour}
\]

Thus, the correct answer is:

**B. 14 miles per hour**
