Rates of change question:
A search light on the ground at S detects and tracks a plane P that is due east of the search light. The plane is flying due west at a constant velocity of 240 km/hr and maintains a constant height of 900 metres above ground level.

Let theta (t) radius be the angle of elevation of the plane at time t seconds and let x(t) kilometres be the distance from S to the point Q on the ground directly below P.

it's such a wordy question so i get confused LOL
