Question 405679
Susan hiked from her camp, going North for exactly 4 miles. Then she made a turn and hiked East exactly 3 miles. Then she wanted to hike back to camp in a straight line back to her camp. How far was she from camp?
.
Apply Pythagorean theorem -- where the hypotenuse is the distance to camp.
.
Let x = distance (hypotenuse) to camp
then
x^2 = 4^2 + 3^2
x^2 = 16 + 9
x^2 = 25
x = 5 miles
