Multiple choice question: A man 6 feet tall walks at 5 feet per second along one edge of a road that is 30 feet wide. On the other side of the road is a light atop a pole 18 feet high. How fast is the length of the man's shadow increasing when he is 40 feet beyond the point directly across the road from the pole? Options are: a) 5/3 ft/sec b) 7/4 ft/second c) 3/2 ft /sec d) 2 ft/sec e) 5/4 ft/second I got 2 ft/s when I solved it, is that correct?
