The minute hand of a clock completes 1 circle in a minute. As the length of the minute hand is 1.12 m, the tip moves in a circle with a circumference of 2*pi*1.12 = 2.24*pi m.
This distance is covered in 1 minute
Therefore the rate of the tip of the minute hand in centimeter per minute is 2.24*100*pi cm/min
Rate in cm/min = 224*pi cm/min
