Related rates... simple? (Will medal:) )

OpenStudy (askme12345):

a person 6 feet tall is walking away from a lamp post at the rate of 59 feet per minute. when the person is 8 feet from the lamp post his show is 10 feet long

OpenStudy (askme12345):

find the rate at which the length of the shadow is increasing when he is 40 feet from the lamp post

OpenStudy (anonymous):

Related rates problems involve finding a rate at which a quantity changes by relating that quantity to other quantities whose rates of change are known. The rate of change is usually with respect to time. So in that former case; in easy words two increasing qualities. He would be at a rate of, 112 feet per minute rate at which the length of the shadow is increasing. Hope this helps, have a nice day! Tag me on anymore math questions you need help with! :)

That doesn't seem to be correct :( Maybe this screenshot will help!

So 6 feet, 59 feet. If your shadow increase was 2 feet wide apart, (in scientific terms), it would therefore be 2 feet increase of shadow. Sorry I'm sort of confused by this.

I'm not quite sure myself, the wording of the question is stumping me. I had the option to view the answer from this online assignment and it came out as 73.75. I now have to answer the same question but with different numbers. SO.. it now reads 54 ft, 8 ft from the lampost, 10 ft long, and the question asks length of the shadow is increasing when he is 24 ft from the lamp-post
