Rate of change problem

[Loibanguti]

A rotating beacon is located 2 miles out in the water. Let A be the point on the shore that
is closest to the beacon. As the beacon rotates at 10 rev/min, the beam of light sweeps down the shore
once each time it revolves. Assume that the shore is straight. How fast is the point where the beam hits the
shore moving at an instant when the beam is lighting up a point 2 miles along the shore from the point A?

How many posts do you plan on making without showing any work? Do you understand what it means to ask for help with a math problems? Since I truly think you don't, I will tell you that it is not asking for a complete solution so you can sit back and watch. Math is not a spectators sport.
