Student Satisfaction is Priority with focus on concept understanding

Solution:

Assume that your friend heads 20 ft east and then 15 ft south, and you head 12 ft west and 9 ft north.

The movement of your friend forms a right angle triangle with base of 20 ft and height of 15 ft

your movement forms a right angle triangle with base of 12 ft and height of 9 ft

The distance that the baseball is thrown is the sum of the hypotenuses of the right angle triangles formed

D = [ √(12^{2} + 9^{2}) + √(20^{2} + 15^{2})] = 15 + 25 = 40 ft
