To determine which student reads faster and by how much, we first summarize their reading rates:
- Student One: 10 pages in 1 hour, which translates to a reading rate of 10 pages per hour.
- Student Two: 30 pages in 2 hours, which translates to a reading rate of 15 pages per hour.
Now, we compare the two reading rates:
- Student One: 10 pages/hour
- Student Two: 15 pages/hour
Student Two reads faster than Student One by:
15 pages/hour (Student Two) - 10 pages/hour (Student One) = 5 pages/hour.
So, Student Two reads faster than Student One by 5 pages per hour.
The correct answer is: B. Student two reads faster than student one by 5 pages per hour.
