Beginning in Town A, Biker Bob rides his bike 30 miles west, 6 miles north, 15 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.) Options:	A) 27 miles	B) 25 miles	C) 24 miles	D) 28.3 miles	E) 23 miles
Using Pythagoras we have one side i,e total distance traveled in north direction = 18+6=

<output>24</output>
24m   other being the base ie distance traveled west- distance traveled eat=30-15= 
<gadget id="calculator">30-15</gadget>
<output>15</output>
15 m   now this third side or the distance between town A and Town B=24^2+ 15^2=sq root 801=28.3m   Answer : 28.3 miles
<result>D</result>
