Question

a person moves along a curved path of semicircle field of radius 14 km reaches one colour to another corner in 11 hours calculate average speed and velocity

Answer 1

Total distance traveled = $\pi r$ = 43.98 km
Average speed = Total distance traveled / time taken = 43.98/11 = 4km/hr
Total displacement traveled = diameter = 28km
Average velocity = Total displacement travel / time taken = 28/11 = 2.55km/hr
