Beginning in Town A, Biker Bob rides his bike 20 miles west, 6 miles north, 10 miles east, and then 18 miles north, to Town B. How far apart are Town A and Town B? (Ignore the curvature of the earth.)
Choose one
A) 28 miles	B) 30 miles	C) 26 miles	D) 18 miles	E) 22 miles

Rationale: using pythagoras we have one side i , e total distance traveled in north direction = 18 + 6 = 24 m other being the base ie distance traveled west - distance traveled eat = 20 - 10 = 10 m now this third side or the distance between town a and town b = 24 ^ 2 + 10 ^ 2 = sq root 676 = 26 m answer : c
Answer: C
