Questions & Step-by-Step Solutions

A train leaves station A at 9:00 AM and reaches station B at 11:30 AM. If the distance is 150 km, what is the average speed of the train?
  • Step 1: Identify the departure time of the train, which is 9:00 AM.
  • Step 2: Identify the arrival time of the train, which is 11:30 AM.
  • Step 3: Calculate the total time taken for the journey. From 9:00 AM to 11:30 AM is 2 hours and 30 minutes.
  • Step 4: Convert 30 minutes into hours. 30 minutes is equal to 0.5 hours.
  • Step 5: Add the hours together. 2 hours + 0.5 hours = 2.5 hours.
  • Step 6: Identify the total distance traveled by the train, which is 150 km.
  • Step 7: Use the formula for average speed, which is Average Speed = Distance / Time.
  • Step 8: Substitute the values into the formula: Average Speed = 150 km / 2.5 hours.
  • Step 9: Calculate the average speed. 150 km divided by 2.5 hours equals 60 km/h.
  • Average Speed Calculation – The average speed is calculated by dividing the total distance traveled by the total time taken.
  • Time Conversion – Understanding how to convert time from hours and minutes into a decimal format for calculations.
