CorrectNot quiteAnswer C

Correct answer: C

Explanation

  1. Pages per minute = 1,080÷45=241{,}080 \div 45 = 24.

  2. Time for 1,800 pages = 1,800÷24=751{,}800 \div 24 = 75 minutes.

  3. 75 minutes = 1 hour 15 minutes.

Worth noting

Writing 75 minutes as '1.75 hours' or '1 hour 25 minutes' is a conversion slip: 75 minutes is 1¼ hours.
