I went 15 km to the North, then turned West and covered 10 km. Then I turned South and covered 5 km, and then I turned East and covered 10 km. In which direction am I going and how far from starting point?
- East, 14.14 km
- North, 10 km
- South, 5 km
- West, 15 km
Explanation
- Start
- Go 15 km North
- Turn West, go 10 km
- Turn South, go 5 km
- Turn East, go 10 km
Now check:
- North 15 km, then South 5 km → Net 10 km North
- West 10 km, then East 10 km → Net 0 km
So, final position is 10 km North of the starting point, and you're facing East (last direction moved).
