Answer
360 pages

The correct answer is 360 pages — Thus he can read 360 pages in 3 hours.

Step-by-step solution

  1. Find pages per minute: 10 pages ÷ 5 minutes = 2 pages per minute.
  2. Calculate minutes in 3 hours: 3 hours × 60 minutes/hour = 180 minutes.
  3. Multiply pages per minute by minutes: 2 pages/min × 180 min = 360 pages.
  4. Thus he can read 360 pages in 3 hours.
Common mistake: Using 3 hours as 3 minutes or miscalculating minutes in hours
