Answer 2

Answer:

The gradient of a displacement-time graph is velocity.

In the graph given, the time taken for the moving from point C to D is 1 second and the displacement is read as 4m.

Velocity is defined as the rate at which an object changes its position.

Hence, in one second, the distance covered is 4m. So the velocity is 4m/s.
