A circular track has a circumference of 3140 m with AB as one of its diameter. A scooterist moves from A to B along the circular path with a uniform speed of 10 m/s. Find

(a) distance covered by the scooterist,


(b) displacement of the scooterist, and


(c) time taken by the scooterist in reaching


from A to B


Circumference = 3140 m



Speed = 10 m/s


a) Distance of scooter = circumference/2


= 3140/2


= 1570 m


b) Displacement of scooter = AB


= circumference/ π


= 3140/3.14


= 1000 m


c) Time taken = distance/speed


= 1570/10


= 157 s
