At 12 noon the hour hand of a clock points to 12. Through how many degrees does it turn between then and 10:18 p.m.?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 309°
The hour hand turns 30° for every hour and 0.5° for every minute.
From 12 noon to 10:00 p.m.: \(10\times30^\circ=300^\circ\)
From 10:00 p.m. to 10:18 p.m.: \(18\times0.5^\circ=9^\circ\)
Total turn \(=300^\circ+9^\circ=309^\circ\)
