Beginning in Town A, Biker Bob rides his bike 12 miles west, 6 miles north, 4 miles east, and then 12 miles north, to Town B. How far apart are Town A and Town B? (Ignore the curvature of the earth.)  Choose the correct choice from the following choices:
A) 18.97 miles  B) 20 miles  C) 22 miles  D) 23 miles  E) 25 miles
Using Pythagoras we have one side i,e total distance traveled in north direction = 12+6=

<output>18</output>
18m   other being the base ie distance traveled west- distance traveled eat=12- 6= 
<gadget id="calculator">12- 6</gadget>
<output>6</output>
6 m   now this third side or the distance between town 18.97 miles and Town B=18^2+ 6^2=sq root 360=18.97 mile   18.97 milesnswer : 18.97 miles
