Answer:since, initial position of minute hand of clock is at 12 and then came to 6.
So, the displacement will be twice of minute hand: 2×7cm = 14cm
------------------
Distance covered by the tip of the minute hand will equal to the half of circumference of circle:
Distance = (2×pie×radius)/2
=pie × 7cm
= 22/7 ×7cm
= 22cm
