In an accurate clock, in a period of 2 hours 20 minutes the minute han...
The minute hand of an accurate clock completes one full rotation every 60 minutes, or 1 hour. Therefore, in 2 hours and 20 minutes, the minute hand will move over 2 full rotations plus an additional 20 minutes.

2 rotations = 2 x 60 = 120 minutes
20 minutes = 20 minutes

So, in a period of 2 hours 20 minutes, the minute hand will move over 120 + 20 = 140 minutes.

Therefore, the correct answer is a) 140.
