The unit rate is 16.4 kilometers per hour.
Solución
To find the unit rate (kilometers per hour), you can divide the total distance traveled by the total time taken.
**Given:**
- Distance = 20.5 kilometers
- Time = 1.25 hours
**Calculation:**
\[
\text{Unit Rate} = \frac{\text{Distance}}{\text{Time}} = \frac{20.5 \text{ km}}{1.25 \text{ hours}} = 16.4 \text{ kilometers per hour}
\]
**Answer:**
The unit rate is **16.4 kilometers per hour**.

To find the unit rate, you simply divide the total distance by the total time. In this case, you take 20.5 kilometers and divide it by 1.25 hours. That gives you a speed of 16.4 kilometers per hour. So, the cyclist is cruising at quite a decent pace! When calculating speed, it's essential to keep your units consistent. This means, if you're measuring distance in kilometers, your time should be in hours. If not, conversions will lead to mistakes and could leave you pedaling in the wrong direction on your calculations!
