Answer 1

say tthey startedd east

east distance = 150 + 120 cos 45
north distance = 120 sin 45

hypotenuse =
sqrt[(150+120cos45)^2+(120sin 45)^2]

Answer 2

missing the distance along the 45° path

Answer 3

I read the question as consisting of 3 legs of the journey.

Funny thing is that I answered the same question back in February, as seen from the Related Question below.
