The correct answer is A) 150°. The hour hand of a clock completes a full circle (360°) in 12 hours. To find the degrees rotated, we calculate the degrees moved per hour and multiply by the number of hours.
– The hour hand moves 360 degrees in 12 hours.
– Degrees moved per hour = 360° / 12 hours = 30° per hour.
– From 12:00 noon to 5:00 pm is a duration of 5 hours.
– Total rotation = 5 hours * 30°/hour.
Calculation: 5 hours * 30°/hour = 150°. Therefore, the hour hand rotates through 150 degrees from 12 o’clock noon to 5 o’clock on the same evening.
