Given,
The time at which the angle between two hands must be calculated = 1:10
To Find,
The angle between the two hands of a clock at 1:10.
Solution,
A clock has twelve equal divisions.
Since for completion of a rotation, it takes 360°,
Value of each division =
⇒
Thus the value for each division is 30°.
For every 360° rotation of the minute hand, the hour hand rotates for 30°.
For 10 minutes, the rotation of minutes hand is 60°.
Thus the rotation of the hour hand can be calculated as follows:
→
→
⇒
⇒
Thus the hour hand rotates 5° while the minute hand rotates 60°, that is 10minutes.
So the angle between the hour hand and the minute hand at 1:10 = (since each division = 30°)
=25°
Henceforth, the angle between the two hands of a clock at 1:10 is 25°.
