Given : Every time the long arm completes a revolution,
the short arm in the stopwatch moves to the next division.
The watch was stopped, when the long arm was 4140° away from its start position.
To Find : the short arm would be how much away from its start position.
60°
66°
69°
72°
Solution:
There are 60 Divisions in stop watch
Every time the long arm completes a revolution,
the short arm in the stopwatch moves to the next division.
=> for every 360° of long arm = (1/60) * 360° of Short Arm
=> for every 1° of long arm = (1/60)° of Short Arm
=> for every 4140° of long arm = 4140 * (1/60)° of Short Arm
=> for every 4140° of long arm = 69° of Short Arm
Hence the short arm would be 69° away from its start position.
