+239 Stacey is standing in a field. She walks 11 meters west, 30 meters north, 4 meters west and finally 22 meters south. How many meters is she from her starting point?
+6251 Let's say Stacey starts at point (0,0)
She walks 11 meters west to (-11,0)
She walks 30 meters north to (-11,30)
She walks 4 meters west to (-15, 30)
Finally she walks 22 meters south to (-15, 8)
she is
\(d = \sqrt{(-15)^2 + (8)^2} = \sqrt{225 + 64} = \sqrt{289} = 17 \text{ meters from her starting point}\)
