Answer:
16.25 m
Explanation:
we know that the equation pf parabola 

from bellow figure the coordinate of parabola is (600,65) that is y=600 and x=65
putting the the value of y and x in the equation of parabola 

k=0.0001805
now the equation is 

we have to find the value of y at x=300m
so 
y=16.25 m
