a 6.5 ft tall car standing next to an adult elephant casts a 33.2 ft shadow. if the adult elephant casts a shadow that is 51.5 ft long then how tall is it?
We can answer this with a proportion :
6.5 / 33.2 = h / 51.5 where h is the elephant's height....cross-multiply
51.5 * 6.5 = 33.2 * h divide both sides by 33.2
51.5 * 6.5 / 33.2 = h = about 10.08 ft
