Answer 2

Answer:

average speed= total distance covered/ Total time taken

total distance = 180 m

total time = 60 sec

average speed = 180 / 60

= 3 m per second

average velocity = displacement/ Time

displacement= 0 m ( as her inital and final position are same)

average velocity = 0/ 60

=0 m per sec
