Questions & Step-by-Step Solutions

A player runs 5 km in 25 minutes. What is his speed in km/h? (2023)
  • Step 1: Understand that speed is calculated by dividing distance by time.
  • Step 2: Identify the distance the player ran, which is 5 km.
  • Step 3: Identify the time it took to run that distance, which is 25 minutes.
  • Step 4: Convert the time from minutes to hours because speed is usually measured in km/h. To do this, divide 25 minutes by 60 (since there are 60 minutes in an hour).
  • Step 5: Calculate the time in hours: 25 minutes / 60 = 25/60 hours.
  • Step 6: Now, use the speed formula: Speed = Distance / Time.
  • Step 7: Plug in the values: Speed = 5 km / (25/60) hours.
  • Step 8: To divide by a fraction, multiply by its reciprocal: Speed = 5 km * (60/25) hours.
  • Step 9: Simplify the calculation: 5 * 60 = 300, and 300 / 25 = 12.
  • Step 10: Therefore, the speed of the player is 12 km/h.
  • Speed Calculation – Understanding how to calculate speed using the formula speed = distance/time.
  • Unit Conversion – Converting time from minutes to hours to ensure consistent units in the speed calculation.
