Through how many degrees does the hour hand of a clock turn in 50 minutes?
Answer and explanation
Correct answer: D. 25°
- Step 1: The hour hand turns 360° in 12 hours, which is 30° per hour. Step 2. That is 0.5° per minute. Step 3. 50 × 0.5° = 25°. Answer: 25°. Why not the others: 30°: This is the turn in a full hour. 300°: This is the turn of the minute hand in 50 minutes. 12.5°: This uses 0.25° per minute instead of 0.5° per minute.
