A body travelled in a straight line as shown in the velocity(v) - time(t) graph. Which distance(s)-time(t) graph correctly represents the motion of the body?

AGraph A

BGraph B

CGraph C

DGraph D

Explanation

During acceleration (0 to t1) the distance-time graph curves upward (concave up), during constant velocity (t1 to t2) it is a straight line, and during deceleration (t2 to t3) it curves and flattens (concave down). Graph B shows this behaviour correctly.
