# The angle of elev

Answer :

Let the B and C be the positions of aero plane. By given information we can make a diagram for the above As the height is constant Let AL = x

Let the speed of plane be y m/s

Then the distance travelled by plane in 15 sec = BC = speed × time = 15y

BC = LM = 15y 

In ABL  x = 1500

AM = AL + LM = x + 15y = 1500 + 15y [from 1]

In ACM  100 + y = 300

y = 200 m/s Rate this question :
