Question

athlete moves around a circular path of radius 70 metre and completes two
and half circular path in 40 minutes calculate the average speed and average velocity​

Answer 1

hi

circumfrence of circle = 2×22/7×70

440m

he completes 2.5 of the path ( 2.5×440) =1100

in 40 mins

so total distance covered in 1 hour = 1650m

so the speed is 1.65kmph

and the velocity changes in this path as the direction of motion is not constant
