Hey mate here is ur answer,hope it helps! :)
Step-by-step explanation:
On an analog 12-hour clock, the number of degrees between each hour mark is 30°. Obviously the third mark at 90° clockwise is used by the minute hand to represent “15 minutes”. Since this is one fourth of the entire circuit that the hand will make in an hour, the hour hand will have moved one quarter of the distance to the next hour mark. Since there are 30 degrees between hours, the answer will be one fourth (0.25) of 30 or 30*0.25.
This can also be written as 30/4.
30*0.25=7.5
30/4=7.5
Incidentally, on a 24-hour analog clock where the minute hand moves the same as a 12-hr clock but the hour hand only moves 15 degrees between hours, the answer would be much different. In this case, the hour hand would be just past 45°CW for 3:15 am or just past 225°CW for 3:15 pm and the minute hand would be at 90°CW. The hour hand would travel 15° between hours so a quarter of that would be 3.75°. The hour hand would be at 45+3.75 degrees for (48.75°) for 3:15 am or at 180+45+3.75 (228.75°) for 3:15 pm.
3:15 am — Subtract 48.75° from 90° and it would give the value of 41.25° between the hands on a 24-hr clock. At 3:15 am the hands are at 41.25° apart.
3:15 pm — Subtract 90° from 228.75° and it will give a value of 138.75°. At 3:15 pm the hands are at 138.75° apart.
