An object is seen at a location 10 m from a well known tree in a direction 30 degrees from the negative y axis towards the positive x axis. 25 seconds later the object is seen at a location 10 m from that same tree in a direction 40 degrees from the positive x axis towards the positive y axis. what is was the average velocity of the object during this time?
