Question 1.

3 o’ clock
Explanation:
The hour hand, the shorter of the two hands, completes 1 rotation ( 360Â° )Â  in 12 hours in a normal 12-hour analogue. The minute hand, the longer hand, completes 1 rotation through 360Â° in 60 minutes.
As the hour hand is pointing 3 and minutes hand is at 12 means 00 minutes
Thus the time is 3 ‘ 0 clock .

Question 2.

Digital clock showing time 3’o clock
Explanation:
In digital clock the time is represented with 4 numbers and two numbers are seperated with a colon in the middle.
