Answer:
The minute hand rotates 210º in [tex]\frac{7}{12}[/tex] hour.
Step-by-step explanation:
The minute hand rotates 360º each hour, then the amount of degrees moved by the minute hand of the clock in [tex]\frac{7}{12}[/tex] hour is determined by the following simple rule of three:
[tex]x = 360^{\circ}\times \frac{7}{12}[/tex]
[tex]x = 210^{\circ}[/tex]
The minute hand rotates 210º in [tex]\frac{7}{12}[/tex] hour.
