hey someone please help me with this.please. A light at eye level stands 20 ft. from a house and 15 ft. from the path leading from the house to the street.A man walks along the path at 6 ft per sec. How fast does his shadow move along the wall when he is 5 ft. from the house?
time-rates
you got a picture?
no i don't have.
the ratio of distances to the man and to the house gives you the ratio for the rates: 20/15 = x/6
i can't see it. the light is not on the path correct?
yes based on the problem it's not bec. its 15 ft. from the path
hey tonks do you know how to solve it?
yes 20/15 = x/6 reduce 4/3 = x/6 mult by 6 24/3 = x 8 = x
tonks i'm sorry the connection is freaking out..
@ tonks can you show the details..pls. solve it step by step please.
just really need your help please...
i must be really dumb because i cannot even draw this picture. the man is walking along the path to the house, but where is the light?
