Aseagull was flying about sea level looking to catch a fish below sea level. the elevation above sea level was 125 1/2 feet. he spots a fish that is 45 1/2 feet below sea level.

the seagull stops exactly half way between his location above sea level and the fish’s location below sea level because he realizes he won’t catch it in time. what’s the seagull’s position in feet at the halfway point? show work.
