How many degrees are there between clock hands at 3.15?

Options

• 0

• 5.5

• 7.5

• 10

Answer 1

7.5

Explanation:

At 3:15 the minute hand will be perfectly horizontal pointing towards 3, whereas the hour hand will move towards 4. Also, the hour hand must have covered `1/4`th of the angle between 3 and 4.

The angle between 2 adjacent digits is 360°/12 = 30°

Hence, 1/4 of 30° = 7.5.
