Answer 2

The graph B and C represents the constant speed of a body.

Given,

A, B, C, and D 4 graphs.

To Find,

The graphs represent the constant speed of a body.

Solution,

In graph A,

We can see that the distance is remaining constant and time is going on. It means the body does not move so there is no speed is there for the body in graph A.

In graph B,

We can see that the distance is increasing with increasing time. The graph is linear. And we know that the slope of the distance-time graph gives us the speed. So, the speed of the body is constant.

In graph C,

We can see that the distance is decreasing with increasing time. The graph is linear. Here, there is a retardation in speed but the speed is constant because the graph has a constant slope. So, the speed of the body is constant.

In graph D,

We can see that the distance is increasing with the increasing time but not linearly. It means the body has speed but is not constant. So, the speed of the body is not constant.

Hence, the graph B and C represents the constant speed of a body.
