Clocks have an hour hand and a minute hand (and sometimes a second hand)
The hour hand is shown in red. It is SHORTER.
The minute hand is shown in green. It is LONGER.
The hour hand uses the numbers shown on the clock face.
It is pointing to between 2 and 3, so we know it is after 2 o'clock but before 3 o'clock.
The minute hand does not use the numbers on the clock face.
We must multiply them by 5 to get the minutes.
It is pointing to 7 which is really 5 x 7 = 35 minutes.
So the time shown is 2:35
There are 25 minutes to go until it is 3 o'clock.
So we can also say that the time is 25 to 3
