Question

Pls ansr this anyone!!​

Answer 1

Answer:

The distance moved by scooterist is equal to the arc AB. The arc AB is half of the circumference.so,

Distance=circumference/2π

= 3140/2×π

=500m

Answer 2

Explanation:

circumference of track =3140m=2πr

radius,r=3140/2π=1570*7/22=499.5

* Distance covered=3140/2=1570m

* Displacement covered=2r=2*499.5=999m

* Time taken=1570/10=157s=2m 37s
