Question

Where will the minutes hand of the clock stop, if it starts at $3O\text{'}$clock and makes $\frac{1}{2}$ of revolution, clockwise?

Answer 1

Finding the position of minutes hand:

We know that $1$ revolution $=360°=60$minutes

$\frac{1}{2}$of revolution $=\frac{1}{2}\times 60$ minutes

$=30$ minutes

If minutes hand starts at $3O\text{'}$clock, then after $30$ minutes, it will stop at $9O\text{'}$clock.

Hence, the minute hand of the clock stop at $9O\text{'}$clock.
