A railway station clock shows exactly 12:00 noon. How many degrees will its hour hand have turned when the clock shows 8:50 p.m.?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 265°
The hour hand turns 30° for every hour and 0.5° for every minute.
From 12 noon to 8:00 p.m.: \(8\times30^\circ=240^\circ\)
From 8:00 p.m. to 8:50 p.m.: \(50\times0.5^\circ=25^\circ\)
Total turn \(=240^\circ+25^\circ=265^\circ\)
