91) A car departs Little Rock, Ark., traveling to a baseball game located nine miles east and 12 miles north of the departure point. About how many miles is the game from the departure point? 

1. 3
2. 63
3. 15
4. 21

Answer 3 is correct. Use the Pythagorean theorem since the directions as given form a right triangle. 9²+12²=c², or 81+144=225². Take the square root, and you're left with 15.
