In many cases, there is a third hand that ticks on seconds
The second hand on the clock circles 420 times in 7 hours.
The second hand of a clock completes one full rotation around the clock face every 60 seconds. Since there are 60 seconds in a minute, the second hand makes 60 rotations in one minute. In an hour, it makes 60 rotations × 60 minutes = 3,600 rotations. Over a 24-hour day, the second hand completes 3,600 rotations × 24 hours = 86,400 rotations.

The second hand of a clock completes one full revolution every 60 seconds. To move from the 3 to the 8 on the clock face, the second hand needs to cover a distance of 5 out of the 60 total seconds on the clock. Therefore, it would take 5/60 or 1/12 of a minute for the second hand to move from the 3 to the 8, which is equivalent to 5 seconds.
If the second hand began at 12, 1200 seconds would pass in this period, or 20 minutes.

The second hand on the clock circles 420 times in 7 hours.
To determine the number of seconds it takes for the second hand of a clock to move from 12 to 2, we need to understand the motion of the second hand. The second hand completes one full revolution (360 degrees) in 60 seconds. The clock face is divided into 12 equal sections, each representing an hour. Each hour section represents: \frac{360^\circ}{12} = 30^\circ When the second hand moves from 12 to 2, it moves across 2 hour sections. Therefore, the angle swept by the second hand is: 2 \times 30^\circ = 60^\circ Since the second hand completes 360 degrees in 60 seconds, it sweeps through 1 degree in: \frac{60 \text{ seconds}}{360^\circ} = \frac{1}{6} \text{ seconds per degree} Therefore, to sweep through 60 degrees, the second hand will take: 60^\circ \times \frac{1}{6} \text{ seconds per degree} = 10 \text{ seconds} Thus, it takes 10 seconds for the second hand to move from 12 to 2.

A 45-second shot clock was introduced in the NCAA men's game in the 1985-86 season. In the 1993-94 season, the shot clock time was reduced to 35 seconds.
