At which point is the body moving with the largest speed?

AMUAMU 2018Motion in a Straight Line

Solution:

As we know that from acceleration-time graph Speed = Area under acceleration-time graph. From the graph, as given in the question
Area is maximum for point $0$ to point $2$
Therefore, the speed of the body is maximum (or largest) at point $2$
