Solution

The correct option is C
Displacement: 5m , Distance: 25m

Total distance Travelled = PR + RQ = 13 + 12 = 25m
Initial position is P and final position is Q.
And as we know length between initial and final position is displacement.
Total displacement = PQ = $\sqrt{13^{2} - 12^{2}}$ = 5m (using Pythagoras' theorem)
