so

by proportion

Find how many rotations will make in [tex]4[/tex] hours

[tex]\frac{1}{1} \frac{rotation}{hour}=\frac{x}{4} \frac{rotation}{hours} \\ \\ x=4\ rotations[/tex]

The minute hand completes 4 rotations between 12:00 noon and 4:00 pm

There are 4 hours between 12:00 noon and 4:00 pm

For each hour, the minute hand completes a rotation

This means that, the minute hand completes 4 rotations in 4 hours

Hence, the minute hand completes 4 rotations between 12:00 noon and 4:00 pm
