Worked practice questions
Ravi walks 5 km north, then 3 km east, then 5 km south. How far is he from the starting point?
- 3 km
- 8 km
- 13 km
- 5 km
Show answer and solution
Correct answer: A. 3 km
North 5 km then south 5 km cancel (net 0 in N-S direction).
**Net displacement:** 3 km east.
**So 3 km from start.**
Anand walks 10 m east, then 5 m north, then 10 m west, then 5 m north. Final direction from start:
- East 10 m
- North 10 m
- South 10 m
- West 5 m
Show answer and solution
Correct answer: B. North 10 m
East 10 m and west 10 m cancel.
North 5 m + north 5 m = north 10 m.
**Final position:** 10 m north of start.
