Question

A tree cast a shadow that is 20 feet long. Frank is 6 feet tall, and while standing next to the tree he cast a shadow that is 4 feet long.
A. How tall is the tree?

B. How much taller is the tree than Frank?

Answer 1

A.  So we know that a 6 foot figure casts a shadow 4 feet long.  4 foot shadow x 5 = a 20 foot shadow.  So this means we take 6 x 5 = 30, and the tree is 30 feet tall.  
B.  30 - 6 = 24 feet taller than Frank 

Answer 2

The tree is 18 ft tall
 and the tree is 12 ft taller than frank
