A street light is mounted at the top of a 15 foot tall pole. A man 6 ft tall walks away from the pole with a speed of 6 ft/s along a straight path. How fast is the tip of his shadow moving when he is 40 ft from the pole?

Attempt

Well actually, I've drawn it out and stuff, but I was wondering if the tip of shadow would be moving in the same speed as the man..

I'm a bit confused at how to tackle this problem.. :/
