Short hand goes around clock 4 times in 2 days.
DIstance travelled
=4×circumference of circle traced by short hand
=4×2π×4
=100.57 cm
Long hand goes around clock 48 times in 2 days.
DIstance travelled =48× circumference of circle traced by long hand
=48×2π×6
=1810.28 cm
Total distance =1810.28+100.57
=1910.85 cm
