A person is walking at 2 m/s on a train moving at 10 m/s. What is the speed of the person relative to the ground?
Correct Answer: 12 m/s
  • Step 1: Identify the speed of the train. The train is moving at 10 m/s.
  • Step 2: Identify the speed of the person walking on the train. The person is walking at 2 m/s.
  • Step 3: To find the speed of the person relative to the ground, add the speed of the train and the speed of the person together.
  • Step 4: Calculate the total speed: 10 m/s (train) + 2 m/s (person) = 12 m/s.
  • Step 5: The speed of the person relative to the ground is 12 m/s.
