Suppose Ms. Kraus is 1.75 m tall. When her shadow is is 1 m, how long would the shadow be of a 265 m tall building? (Make a sketch to help solve the problem)

With the same sunlight angle, the height-to-shadow ratio is the same for Ms. Kraus and the building. Set up 1.75/1 = 265/x, where x is the building’s shadow length; solving gives x = 265/1.75 ≈ 151.4 m. So the shadow is about 151 m, choice B.
