Answer : 4. "215 degrees"
Explanation :

Answer: D) 215 degrees Explanation: The total angle traced by the hour hand is the angle traced in 7 hours and 10 minutes.We know that the angle traced by the hour hand in one hour is 30º and in one minute is 1/2º.Therefore, (30º x 7) + (10 x 1/2º) = 215º is the angle traced by the hour hand.
