Questions & Step-by-Step Solutions

If a sound wave travels 1 km in 3 seconds, what is its speed?
  • Step 1: Identify the distance the sound wave travels. In this case, it is 1 km.
  • Step 2: Convert the distance from kilometers to meters. 1 km = 1000 meters.
  • Step 3: Identify the time it takes for the sound wave to travel that distance. Here, it is 3 seconds.
  • Step 4: Use the formula for speed, which is Speed = Distance / Time.
  • Step 5: Plug in the values: Speed = 1000 meters / 3 seconds.
  • Step 6: Calculate the speed: 1000 divided by 3 equals approximately 333.33 meters per second.
  • Step 7: Round the answer to a simpler number if needed. Here, we can say the speed is approximately 333 m/s.
  • Speed Calculation – Understanding the formula for speed, which is distance divided by time.
  • Unit Conversion – Converting kilometers to meters to ensure consistent units in calculations.
