Answer:
Explanation:
Total displacement towards north = 2.50 km - 4.3 km + 1.4 km
= -0.4 km
Displacement is a vector quantity so we took negative sign when direction reversed.
Total distance travelled = 2.5 + 4.3 + 1.4 km
= 8.2 km
Distance is a scalar quantity so no reversal of sign on reversal of direction.
