Question

Where will the hand of a clock stop if it

a)Starts at $12$ and makes $\frac{1}{2}$ of a revolution, clockwise?

b)Starts at $2$ and makes $\frac{1}{2}$ of a revolution, clockwise?

c)Starts at $5$ and makes $\frac{1}{4}$ of a revolution, clockwise?

d)Starts at $5$ and makes $\frac{3}{4}$ of a revolution, clockwise?

Answer 1

$\frac{1}{2}$ revolution clockwise exceeds the time by $6$ hrs so $12$ becomes $6$

$\frac{1}{2}$ revolution clockwise exceeds the time by $6$ hrs so $2$ becomes $8$

$\frac{1}{4}$ revolution clockwise exceeds the time by $3$ hrs so $5$ becomes $8$

$\frac{3}{4}$ revolution clockwise exceeds the time by $9$ hrs so $5$ becomes $2$
