From 10 am to 10.30 am minute hand rotates 180° from 0 minute to 30 minutes.
Hence distance covered is half the circle means semi circle.
distance= perimeter of semi circle
distance= πr
distance= 22/7 ×10. ( r=10cm)
distance= 3.14×10= 31.4 cm
displacement is twice the length of the hand
Displacement= 2×r= 2× 10= 20cm
Hence Distance is 31.4 cm & Displacement is 20 cm.
Hope this will help you....
