Two teams are playing a game of tug-of-war. Team's A starting position is represented by the point (11,9). A flag in the middle of the rope represents
the midpoint and its location is (17,21).
a) What is the point that represents the starting position of Team B?
b) In order to win the game, either team must pull the flag half way
between the midpoint and the team's starting point. Give the location the
flag must reach in order for each to win. In other words, what is the
Midpoint between Team A's starting position and the flag, and what is the
Midpoint between Team B's starting position and the flag.
