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?

Answer 1

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
