Dear friend,
The area under VELOCITY -TIME GRAPH GIVES YOU DISPLACEMENT (DISTANCE WITH DIRECTION)
The slope of the distance-time graph gives you speed.
AS-------v = s(with direction)/t
and vt = s(with direction)
V = s/t
Where
s = DISTANCE
t = TIME
s ( with direction ) =DISPLACEMENT
V = speed
v = VELOCITY
hope my answer will help you
