Question

Measure of the angle that the minute hand rotates on a round clock in one hour is degrees.

Answer 1

We know that the minute hand completes one full circle in an hour.
It can be observed from the figure that the minute hand rotates one full angle in 1 hour.
$\because$ $1$ full angle $={360}^o$

Hence, the measure of the angle that minute hand rotates in one hour is ${360}^o$.
