The velocity can be calculated by dividing the displacement (change in position) by the time taken:

Average velocity = displacement / time

In this case, the paper airplane flies 26 meters towards the west, which we can take as the negative x-direction, and the time taken is 20 seconds. So:

displacement = -26 meters
time = 20 seconds

Substituting these values into the formula gives:

Average velocity = -26 meters / 20 seconds

Simplifying this expression gives:

Average velocity = -1.3 meters/second towards the west

So the average velocity of the paper airplane is 1.3 meters/second towards the west (in the negative x-direction).
