At a given time, the height of an object is directly proportional to the length of the shadow that is cast on the ground. A person 6 feet tall casts a shadow 1 foot long at noon. a) What is the length of the shadow cast by a flagpole known to be 20 feet tall? b) A tree cast a shadow of 3 feet. How tall is the tree?

  1. 6/1 = 20/h
    h = 20/6 = 10/3 = 3.33

    6/1 = t/3
    t = 18
