travelled by the car.
NECO 2008

Answer 1

360

Step-by-step explanation:

The total distance travelled by the car can be calculated by finding the area under the velocity-time graph [1]. To do this, you first need to calculate the area of the rectangle formed by the points (0, 0), (5, 15), (15, 22) and (20, 0). This area is equal to 250. Then you can calculate the area of the triangle formed by the points (5, 15), (15, 22) and (20, 0). This area is equal to 110. Adding these two areas together gives a total distance of 360.
