Question: If a train travels 120 km in 2 hours, what is its speed in m/s?

Options:

Correct Answer: 20 m/s

Solution:

Speed = Distance / Time = 120 km / 2 h = 60 km/h = (60 * 1000) / (3600) = 16.67 m/s.

If a train travels 120 km in 2 hours, what is its speed in m/s?

If a train travels 120 km in 2 hours, what is its speed in m/s?

Step 1: Identify the distance traveled by the train, which is 120 kilometers.
Step 2: Identify the time taken for the journey, which is 2 hours.
Step 3: Calculate the speed in kilometers per hour (km/h) using the formula: Speed = Distance / Time.
Step 4: Substitute the values into the formula: Speed = 120 km / 2 h = 60 km/h.
Step 5: Convert the speed from kilometers per hour to meters per second (m/s).
Step 6: Use the conversion factor: 1 km/h = 1000 meters / 3600 seconds.
Step 7: Multiply the speed in km/h by the conversion factor: 60 km/h * (1000 m / 3600 s).
Step 8: Calculate the result: (60 * 1000) / 3600 = 16.67 m/s.
