An ant travels along a right angled triangle △ PQR first from P to R, then from R to Q. Find the displacement and distance travelled by the ant?
Given, PR = 13 m, RQ = 12 m
- Displacement = 25 m
Distance = 25 m - Displacement = 25 m
Distance = 5 m - Displacement = 5 m
Distance =5 m - Displacement = 5 m
Distance = 25 m

- Distance = 30 m
Displacement = 30 m - Distance = 0 m
Displacement = 30 m - Distance = 0 m
Displacement = 0 m - Distance = 30 m
Displacement = 0 m
