A street light is mounted at the top of a 15-ft-tall pole. A man 6 ft tall walks away from the pole with a speed of 5 ft!s along a straight path. How fast is the tip of his shadow moving when he is 40 ft from the pole? The answer is 25/3. I let x be the length of shadow, y be the distance between man and pole. I did 6/15=x/(x y) then i got x=2/3y dx/dt=dy/dt(2/3) Then I...
