In an ordinary clock, the minute hand would have moved how many degrees over a period of exactly 2 hours and 20 minutes?

Solution

✅ Correct Option: 3

The minute hand covers 360 degrees in 60 minutes, so it moves 6 degrees per minute.

2 hours 20 minutes = 140 minutes.

Total turning =140×6=840= 140 \times 6 = 840 degrees.
