If Betsy leaves Town A traveling due east for 6 miles to Town B, then turns due north and travels 9 miles to Town C, how far will her trip home be to Town A as she travels directly southwest?
If she travels directly southwest she will pass by Town A. It is not quite in that direction.
They probably just want the distance to Town A, which would be sqrt[(6^2) + (9)^2] = sqrt(117) = 10.8 miles
