Show the answer and the worked solution
Correct answer: B. South
Worked solution
- South 10; left → east 10; right → south 5; right → west 10.
- East–west: 10 east and 10 west cancel.
- North–south: 10 + 5 = 15 m south.
- He is due south of home.
Answer: South.
The idea
Label each leg with its compass direction before totalling. The turns matter only for working out those labels.
Shortcut. Only the direction is asked, so check signs: the two 10 m sideways legs are opposite and cancel, and no leg ever points north — due south.
Common trap. "East" — the most tempting wrong pick: the first left from south correctly points east, and a solver who drops the final westward leg sees him end up east of home.
