Answer:
a) Distance = 8km ( 1 block = 1km)
∴ , Distance covered = 8km
b)Displacement -
Let the displacement be d
⇒ d² = 5² + 3² (Pythagoras Theorem )
⇒ d² = 25 + 9
⇒ d² = 34
Explanation:
Distance is the total distance covered hence it is 8km ie. 5km (a to b)+3km (b to c)
The magnitude of displacement will ONLY THE NUMBER , NOT THE UNIT .

Answer:
a) Distance =ab+bc=5+3= 8km ( 1 unit of the graph = 1km)
∴ Distance covered = 8km
b)Displacement -
Let the displacement be d
⇒ d² = 5² + 3² (Pythagoras Theorem )
⇒ d² = 25 + 9
⇒ d² = 34
Explanation:
Distance is the total distance covered hence it is 8km ie. 5km (a to b)+3km (b to c)
