(1) Area under the curve of velocity-time graph is Net distance travelled by the object
 
(2) if slope is positive it is accelerated motion , if slope is negative it is retarded motion and if slope is zero acceleration is zero.
 
(3) If slope is constant , then acceleration is uniform else acceleration is not uniform

Starting from rest, an object is uniformly accelerated to a speed of 60m/s in 20s. The object travels with this speed for next 40s and is then brought to rest by a uniform retardation in the next 30s.Sketch velocity time graph and calculate the acceleration, retardation and the total distance travelled. Hint: acceleration =rate of change of velocity.  distance covered =area under velocity-time graph .
