Answer:

55.

Step-by-step-explanation:

In a velocity/time graph like this the total displacement is the area of the body.

This is the area of (from left to right) of triangle OBF + area of the 2 rectangles + area of triangle CDE

Here this is 1/2 * 2 * 5 + 5 *4 + 5 * 4 + 1/2 * 5 * 4

= 5 + 20 +  20 + 10

= 55.
