180 degrees counterclockwise because 360 degrees is a full circle and 180 is half a circle because 6x2=12

Answer: 180 degrees counterclockwise rotation


Step-by-step explanation:

Given: The clock was running 30 minutes faster.

To correct it Hilary turn the minute hand back 30 minutes, which means a anticlockwise rotation.

We know that a full rotation in a clock is of [tex]360^{\circ}[/tex].

Total time taken by minute hand to complete the rotation is 60 minutes.

Therefore,

[tex]60\ minutes=360^{\circ}\\\Rightarrow1\ minute=\frac{360^{\circ}}{60}\\\Rightarrow30\ minutes=\frac{360^{\circ}}{60}\times30\\\Rightarrow\ 30 minutes= 180^{\circ}[/tex]

Hence, the rotation of the minute hand is 180 degrees counterclockwise rotation.
