Answer 1

The slope of this displacement time graph gives the velocity.

So, here

The slope of car C is zero because the car C is at rest as we can see from the graph, the carC is not displacing with respect to time.

The slope of car B is steeper or more than the slope of the car A.

---------------------------------------------------------------------------------

Slope is determined by finding the tan of the angle it meets with the positive x-axis or the ratio of (change in y coordinates and change in x-coordinates).

---------------------------------------------------------------------------------

So, the required answer is car B.
