Question

pls ans this question

Answer 1

Area under the curve of a velocity time graph gives the displacement of the body.

=1*20/2 + 6*20 + 2*10/2
=10 + 120 + 10
=140m

here, the motion is in straight line
Hence, Distance covered = Displacement = 140m

So, (3) 140,140 will be the answer

Answer 2

As it is given inthe question that the particle moved in a straight line, so the displacement and the distance will be equal

Distance/Displacement in velocity-time graph is given by the area under the curve.

The area under the curve in this case
=[(1/2)x1x20]+[6x20]+[(1/2)x2x10]
=10+120+10
=140

So, the correct option is Option 3
