Answer 1

Hint:Determine the total area under the curve. The area under the velocity time graph of an object gives the displacement of the object. But the total sum of the area above and under the time axis or x-axis gives the total distance traveled by the object and the resultant of the sum of area above the time axis and difference of area below the time axis gives displacement of the object.

Complete step by step answer:

We know that the distance traveled by the body can be determined by taking the sum of the total area under the velocity time graph of the body. Let us name the areas under the above velocity time graph as follows:
