Answer:
The seagull's position halfway is 85.5 feet.
Step-by-step explanation:
The seagull is at 125 1/2 feet above the sea level.
The fish is at 45 1/2 feet below the sea level.
The distance between the seagull and fish = seagull's distance above the sea level + fish's distance below the sea level
                         = 125 1/2 + 45 1/2
                         = [tex]\frac{251}{2}[/tex] + [tex]\frac{91}{2}[/tex]
                         = [tex]\frac{342}{2}[/tex]
                         = 171
The distance between the seagull and fish is 171 feet.
Since the seagull stops halfway, then;
seagull's position = [tex]\frac{171}{2}[/tex]
               = 85.5
The seagull's position halfway is 85.5 feet.
