Answer 3

Calculating the Time for a Quarter Turn of the Minute Hand

To calculate the time it takes for the minute hand to make a quarter turn, we can use the formula: \[ \text{Time} = \frac{360}{\text{degrees per minute}} \]

Given that the minute hand covers 360 degrees in 60 minutes, we can calculate the time it takes for a quarter turn.

Using the formula: \[ \text{Time} = \frac{360}{\frac{360}{60}} \] \[ \text{Time} = 60 \]

Therefore, the minute hand takes 60 minutes to make a quarter turn.
