Explanation:
Circumference of track = 2πr
= 2 × 22/7 × 7 = 44m
displacement = 44÷2 = 22
distance traveled = 44×5.5 = 242m

Answer:
Distance = 22000 m
Displacement = 0
Explanation:
Circumference = 2πr= 44cm= 0.44m
Distance covered in 1 hr= 44km= 44000m
Distance covered in 1/2 hr= 44000/2= 22000m
Displacement will be zero
