Question

a boy who is 5 ft tall casts a shadow 2 ft long find the height of the pole if it casts a shadow 2 ft yards long

Answer 1

if b is 5 ft and b's shadow is 2 ft then for every 2.5 ft the shadow gets 1 foot longer 
2.5 x how long the shadow is. 2 yards is 6 feet so 2.5 x 6 = 15 ft. the pole is 15 feet tall or 5 yards tall
