I am particularly confused by the usage of the word "distance" in the question stem as below - looks more of a displacement rather than a distance but I may be thinking too much

Select possible approximate distances from Malefeco for Alice and Joseph at the end of their respective journeys consistent with the information above.

Alice 42, Joseph 25

In terms of time:
Alice traveled 30 min (east) and 30 min (south)
Joseph traveled 40 min (north) and 30 min (west)

In terms of distance:
If Alice travel at 1 yard/min --> Joseph travel at 0.5 yard/min
Alice traveled 30\sqrt{2} yards (it's a 45-45-90 triangle), which is approximately 42 yards.
Joseph traveled 25 yards (30-60-90 triangle --> 15-20-25 or a 3-4-5 ratio)
