Answer:
8 miles
Step-by-step explanation:
Britney went from -4 to 6, or 10 miles, and then from 10 to -14, or 24 miles. Add these together and Britney traveled 34 miles
Alice went straight from the library to school, so we need to find the hypotenuse of the triangle. Use the Pythagorean theorem (a^2 + b^2 = c^2) and substitute 10 for a and 24 for b to get 100 + 576 = c^2 or 676 = c^2
Take the square root of 676 to get 26 for Alice's distance.
34-26=8
