To find out where the second student finishes, we first determine the distance that the second student runs. Since each student runs approximately \( \frac{2}{11} \) miles, we calculate the total distance covered by the first student as well before the second student starts running. The first student runs \( \frac{2}{11} \text{ mi} \). Therefore, the second student will start running after the first student has finished their leg of the race. Here's how you can calculate it step by step: 1. **Distance the first student runs:** \[ D_1 = \frac{2}{11} \text{ mi} \] 2. **Distance covered by the first student before the second student starts:** \[ D_1 = 0.1818 \text{ mi} \, (\text{approximately}) \] 3. **Distance the second student runs:** The second student also runs \( \frac{2}{11} \text{ mi} = 0.1818 \text{ mi} \). 4. **Total distance covered by the first and second students:** \[ D_{\text{total}} = D_1 + D_2 = 0.1818 \text{ mi} + 0.1818 \text{ mi} = 0.3636 \text{ mi} \] Now, we need to determine between which two markers this distance lies. The course has a marker every 0.1 miles: - The markers are at: - 0.0 mi - 0.1 mi - 0.2 mi - 0.3 mi - 0.4 mi The total distance covered by the second student is approximately 0.3636 miles, which is just shy of the 0.4-mile marker. Therefore, the second student finishes between the 0.3-mile marker and the 0.4-mile marker.
