Question

Through what angle, in degrees, does the minute hand of a clock rotate in $25$ minutes?

Answer 1

We know for the minute hand,

$$\begin{gathered} 60minutes=360° \\ \Rightarrow 1minutes=\frac{360}{60} \\ \Rightarrow 25minutes=\frac{360}{60}\times 25=150° \end{gathered}$$

Hence, in $25$ minutes, the minute hand of a clock rotate $150°$.
