Worked Solution

Step 1: Compare the minutes. The end time has 10 minutes and the start time has 35 minutes. Since 10 Step 2: Rewrite the end time after borrowing: 17:10 → 16 hours and (60 + 10) minutes = 16:70 Step 3: Subtract the start time: Hours: 16 − 14 = 2 hours Minutes: 70 − 35 = 35 minutes Answer: The fair lasts 2 hours 35 minutes.

Correct answer: 2 hours 35 minutes
