Answer:
Step-by-step explanation:
h= 1000 ft
dx/dt= 232 ft/sec
D= 1600 ft
First, we have to find a distance x ( shown in the figure)
applying pythagorus theorem
D^2= h^2+x^2................1
x^2= D^2-h^2
= 1600^2-1000^2
x^2= 1560000
x=1248.99 m
Now we can find out how fast the aircraft is receding from the trawler
( notice that the height is not changing)
so differentiating equation 1 w.r.t t we get
2DD'= 2hh'+2xx'
now putting values we get
