Answer 2

Length of minute hand = 20 mm

Distance covered in one minute = circumference of clock

                                                 = 2πr

                                                = 2*22/7*20

                                               =  880/7 mm

Distance covered in half hour = 880/7*30

                                                = 3,771.42 mm
