Question

You start at point A and walk 4 miles north, then 7 miles east, then 1 mile north, then 5 miles east to get to point B. How far is point A from point B in a straight line, or as the crow flies, as my mom used to say?

Answer 1

Answer:

13 miles.

Step-by-step explanation:

These distances form a right angled triangle with legs 4+1 = 5 and  (7+5) = 12 miles and the distance between A and B is the hypotenuse.

So the distance AB^2 = 5^2 + 12^2 = 169

AB = sqrt 169 = 13 miles.
