Step 1

In a velocity-time graph , the area under the graph represent the displacement.

For first 4 second, displacement is given by the area of the triangle having height , h = V and base length = 4

So the displacement in first 4 second is given as

Step 2

For next 2 second, displacement is given by the area of the rectangle having height , h = V and width = 2

So the displacement in next 2 second is given as

Step 3

For next 2 second, displacement is given by the area of the triangle having height , h = V a...
