Answer:
The second student finishes between the marker at 0.9 mi and the marker at 1.0 mi. Here's how we can determine this: 1. Since each student runs approximately 1 mi, the first student finishes at the marker at 1.0 mi. 2. The second student starts running after the first student and finishes approximately 1 mi after the first student started. This means the second student finishes between the markers at 1.0 mi and 2.0 mi. 3. We know that there is a marker every 0.1 mi, so the second student finishes between the markers at 1.0 mi and 1.1 mi, which is equivalent to 0.9 mi and 1.0 mi. So, the second student finishes between the marker at 0.9 mi and the marker at 1.0 mi.
