Question 1142051
A diagram could be drawn from the description.
You already have this yourself so you can simply label the parts.


Time in seconds after pass overhead, {{{t}}}
Vertical leg, 5000 feet
Horizontal leg, {{{300*t}}} feet
Hypotenuse, h


{{{h^2=(300t)^2+5000^2}}}

{{{h=sqrt(90000t^2+25000000)}}}


Can you continue and finish?
