Question

Dana bikes 10 miles in 50 minutes.

At this rate, how far can she bike in 90 minutes?

Enter your answer in the box.

Answer 1

To determine how far Dana can bike in 90 minutes at her current rate, we first need to find her biking speed in miles per minute.

Dana bikes 10 miles in 50 minutes, so her speed is:

\[
\text{Speed} = \frac{10 \text{ miles}}{50 \text{ minutes}} = 0.2 \text{ miles per minute}
\]

Next, we need to calculate the distance she can bike in 90 minutes at this speed:

\[
\text{Distance} = \text{Speed} \times \text{Time} = 0.2 \text{ miles per minute} \times 90 \text{ minutes} = 18 \text{ miles}
\]

Thus, Dana can bike **18 miles** in 90 minutes.
