Questions & Step-by-Step Solutions

Two trains are moving towards each other on parallel tracks. Train A is moving at 60 km/h and Train B at 90 km/h. What is their relative speed?
Correct Answer: 150 km/h
  • Step 1: Identify the speed of Train A, which is 60 km/h.
  • Step 2: Identify the speed of Train B, which is 90 km/h.
  • Step 3: To find the relative speed of two objects moving towards each other, add their speeds together.
  • Step 4: Calculate the relative speed by adding 60 km/h (Train A) and 90 km/h (Train B).
  • Step 5: The calculation is 60 km/h + 90 km/h = 150 km/h.
  • Step 6: Therefore, the relative speed of the two trains is 150 km/h.
