easy 2 marks Class 9 · Science · Motion
Answer
Displacement: 3 km east; Distance: 5 km

The correct answer is Displacement: 3 km east; Distance: 5 km — Total distance = 4 km + 1 km = 5 km

Step-by-step solution

  1. Displacement = 4 km east – 1 km west = 3 km east
  2. Total distance = 4 km + 1 km = 5 km
Common mistake: adding distances with opposite directions

Concept tested: displacement vs distance
