[Free] Nicole just finished a 5-mile walkathon that took her 1.4 hours. Assume she walks at a constant rate. Let [tex]y[/tex] represent the distance Nicole walks in [tex]x[/tex] hours. Describe Nicole's walking at a constant rate as a linear equation. **Explanation:** 1. Calculate Nicole's walking rate (speed): \[ \text{Rate} = \frac{\text{Distance}}{\text{Time}} = \frac{5 \text{ miles}}{1.4 \text{ hours}} \approx 3.57 \text{ miles per hour} \] 2. The linear equation representing her walking at a constant rate is: \[ y = 3.57x \] Here, [tex]y[/tex] is the distance walked, [tex]x[/tex] is the time in hours, and 3.57 is her walking speed in miles per hour.
