Worked Solution

Step 1: Find the printing rate (pages per minute). Rate = 36 ÷ 4 = 9 pages per minute. Step 2: Convert the total time to minutes. 1 hour 15 minutes = 60 + 15 = 75 minutes. Step 3: Multiply rate by time to find total pages. Total = 9 × 75 = 675 pages. Answer: 675

Correct answer: 675
