One side of a right triangle is +900+ m
The hypotenuse is +1500+ m
Let +s+ = the unknown side
--------------------------------------
+1500%5E2+=+s%5E2+%2B+900%5E2+
+2250000+=+s%5E2+%2B+810000+
+s%5E2+=+1440000+
+s+=+1200+
She ran 1200 m south
---------------------------
Note this is a 3-4-5 triangle
+900%2F300+, +1200%2F300+, +1500%2F300+
+3+, +4+, +5+
