Fluffy the cat creeps 400 m along the floor chasing his prey in an easterly direction. Calculate his velocity if it takes him 40 seconds to do this.

10m/s due east

Explanation:

Given parameters:

   Displacement of fluffy = 400m due east

   Time taken  = 40s

Uknown:

Velocity of the cat =?

Solution:

Velocity is a physical quantity. It is a vector quantity that has both magnitude and direction.

  Mathematically;

       Velocity  =

Insert the parameters and solve;

      Velocity  =  = 10m/s due east.

the answer is blue river
