What is the average velocity of a car that moved 40 km east and 80 km west in 2

The correct option is A.

Step-by-step explanation:

In the given figure the scale is defined as

1 units = 5

Right endpoint of the line represents maximum value. Right endpoint of the line is at 130 because

Left end of the box represents lower quartile. Left end of the box is at 10 because

0+2 units = 10

Since the box plot was created by using a maximum of 130 and a lower quartile of 10, therefore option A is correct.
