Answer 1

To compare the reading rates of Students 1 and 2, we first need to calculate the reading rates of both students.

**For Student 1 (from the graph):**
- The reading rate can be determined from the points on the line. For example:
- At 1 hour, Student 1 reads 10 pages (10 pages/hour).
- At 2 hours, Student 1 reads 20 pages, and so on.

The reading rate for Student 1 is constant:
- 10 pages in 1 hour (which is 10 pages/hour).

**For Student 2 (from the table):**
- We can calculate the reading rate for each interval:
- From 2 to 3 hours: 45 - 30 = 15 pages in 1 hour (15 pages/hour).
- From 3 to 4 hours: 60 - 45 = 15 pages in 1 hour (15 pages/hour).

The reading rate for Student 2 is also constant:
- 15 pages in 1 hour (which is 15 pages/hour).

**Comparison:**
- Student 1 reads at a rate of 10 pages/hour.
- Student 2 reads at a rate of 15 pages/hour.

**Conclusion:**
Student 2 reads faster than Student 1 by:
15 pages/hour - 10 pages/hour = 5 pages/hour.

So the correct response is:
**Student 2 reads faster than Student 1 by 5 pages per hour.**
