Solution
The slope of a displacement-time graph gives the velocity of the body. The more slanted or steep displacement-time graph has a large magnitude of velocity. On the other hand, a less slanted or less steep displacement-time graph has a less magnitude of velocity.
From the given displacement-time graph we can observe that the slope of line A is more than the slope of line B so vehicle A is moving with a greater velocity than vehicle B.
