A street light is mounted at the top of a 14 ft tall pole. A woman 6 ft tall walks away from the pole with a speed of 6 ft/sec along a straight path. How fast is the tip of her shadow moving when she is 45 ft from the base of the pole?

Best ResponseYou've already chosen the best response.0Okay so cantorset, this is what im doing: y/6 = (y+x)/14 => look at that in terms of similar triangles. Cross multiply and simplify: 14y = 6x + 6y 14(dy/dt)=6(dx/dt) + 6(dy/dt) 8 d(y/dt) = 6 (dx/dt) 8(dy/dt) = 6 * 6 8(dy/dt) = 36, solve for dy/dt = 9/2. What am I doing wrong?
