amy goes for her morning walk. she walks 100 m east in 2 minutes. she then walks 200 m north in 4 minutes. which is true about the velocity with which she walks? a the velocity with which amy walks changes because the direction in which she walks varies. b the velocity with which amy walks is constant because the speed at which she walks is constant. c the velocity with which amy walks changes because the speed at which she walks varies. d the velocity with which amy walks is constant because the direction in which she walks is constant.

Answer :

The velocity with which Amy walks is constant because the speed at which she walks is constant.

Speed is the rate at which an object moves.

Distance is the total movement of an object without any regard to direction.

The formula for speed - distance - time is mathematically given as:

                                   Speed = Distance/Time

  • Here she first walks 100 m east in 2 minutes. i.e. Speed = 50 m/min
  • Then she walks 200 m north in 4 minutes. i.e. Speed = 50 m/min

In both the cases, speed remains constant.

So the velocity with which Amy walks is constant because the speed at which she walks is constant.
