Answer:
v = 0.83 m/s Towards East
Step-by-step explanation:
As we know that average velocity is defined as

here we know that the displacement is 50 meter towards east
and the total time taken must be 60 s to beat all
So here we will have

now we will have

direction of this velocity will be same as the direction of displacement so correct answer will be
v = 0.83 m/s towards east
