How long will it take Jan to type 100 pages if he types at an average rate of 12 pages per hour?

• A. 8 hours and 10 minutes
• B. 8 hours and 15 minutes
• C. 8 hours and 20 minutes
• D. 8 hours and 30 minutes

Answer: (C)

To determine how long it will take Jan to type 100 pages, you divide the total number of pages by the rate at which he types. Jan types at a rate of 12 pages per hour. First, calculate the time in hours: Time (in hours) = Total pages / Typing rate = 100 pages / 12 pages per hour. Doing the math: 100 ÷ 12 = 8.3333 hours. This decimal can also be expressed as 8 hours and 20 minutes. To find the minutes, take the decimal part (0.3333) and multiply it by 60, since there are 60 minutes in an hour: 0.3333 × 60 = 20 minutes. So, the total time it takes Jan to type 100 pages is 8 hours and 20 minutes. This reasoning confirms that the correct answer is indeed the duration that corresponds to this calculation.
