Questions & Step-by-Step Solutions

A train takes 10 seconds to cross a pole. If the train is 150 meters long, what is its speed?
  • Step 1: Identify the distance the train travels while crossing the pole. The train is 150 meters long.
  • Step 2: Identify the time it takes for the train to cross the pole. The time is 10 seconds.
  • Step 3: Use the formula for speed, which is Speed = Distance / Time.
  • Step 4: Plug in the values: Speed = 150 meters / 10 seconds.
  • Step 5: Calculate the speed: 150 divided by 10 equals 15.
  • Step 6: Conclude that the speed of the train is 15 meters per second.
  • Speed Calculation – Understanding the formula for speed, which is distance divided by time.
  • Unit Consistency – Ensuring that distance and time are in compatible units (meters and seconds).
