Answer key and explanations

A. \(50\) minutes
From \(9:15\) to \(10:15\) is 60 minutes. The class ends at \(10:05\), 10 minutes earlier: \(60 - 10 = 50\) minutes. Distractor C (just adds 1 hour), B (off-by-5), D (subtracts too much).
A. \(2:11\)
The minute hand points to 11 minutes (just past the 2), and the hour hand is just past 2. The time is \(2:11\).
B. \(35\) minutes
From \(3:20\) to \(3:55\): \(55 - 20 = 35\) minutes. Distractor A (off-by-5), C (over-count), D (reads 20 as just the hour).
A. Option A
At \(8:42\), the minute hand is between 8 and 9, and the hour hand is between 8 and 9 closer to 9. Option A shows this correctly.
A. \(12:25\) PM
Noon is \(12:00\) PM. \(12:00 + 25 \text{ min} = 12:25\) PM. Distractor B (off-by-10), C (full hour), D (adds extra hour).
A. \(8:40\) PM
From \(7:05\) to \(8:05\) is \(60\) minutes. \(95 - 60 = 35\) more minutes. \(8:05 + 35 \text{ min} = 8:40\) PM.
B. \(6:36\)
The minute hand points to 36 minutes, just past the 7. The hour hand is between 6 and 7, closer to 7. The time is \(6:36\).
B. \(6\) hours \(45\) minutes
From \(8:30\) AM to \(3:30\) PM is \(7\) hours. School ends \(15\) minutes earlier, so the day is \(6\) hours \(45\) minutes.
