Average speed question about a hovercraft

[Triple take]

Homework Statement

This question is about a hovercraft.

Relevant Equations

Vav= V1+V2/2

I assumed since both pass the points they must have the same speed at both instances, so the average speed would be 15 and the speed when passing the object should be 30, since the equation of average speed.

The question does not ask for average speed. Did you attach the wrong image?

Also note that it is much preferred that you type out the actual question rather than just attach an image.
