Answer 2

Answer:

DISTANCE COVERED IN 30 MINUTES= 2.604CM

Step-by-step explanation:

CLOCK MOVES IN CIRCULAR MOTION

SO CIRCUMFERENCE= 2$\pi$R

                                     =2*22/7*2

                                     = 12.5 APPROX

DEGREE COVERED IN 30 MINUTES=360/60*12.5

                                                           75DEGREE

DISTANCE COVERED IN I DEGREE= 12.5/360

                                                           = 0.034DEGREE

DISTANCE COVERED IN 30 MINUTES= 12.5/360*75= 2.604CM
