Math Problem of the Week - Middle School - May 23, 2021 to May 29, 2021

Middle School: 

Question: A 9-foot tree casts a 6-foot shadow. Cameron's dog casts a 2-foot shadow. Cameron is twice as tall as the dog. How tall is Cameron?

Answer: 6 feet

Solution: The tree’s shadow’s length is two-thirds the height of the tree. So, the length of the dog’s shadow is two-thirds its height; 2 feet is two-thirds of 3 feet, so the dog must be 3 feet tall. That means that Cameron is 6 feet tall because he’s twice as tall as the dog.
