Answer :

A gannet initial elevation is 24 1/2 ft

it increases its elevation by 5ft then the elevation is 5 + 24 1/2 = 29 1/2 ft

now it dives 47 2/3 ft

so the final elevation is,

[tex]29\frac{1}{2}-47\frac{2}{3}[/tex][tex]=\frac{59}{2}-\frac{143}{3}[/tex]

[tex]=\frac{177-286}{6}=\frac{-109}{6}[/tex]

so its elevation below to the sea level is -109/6 or -18 1/6 ft
