Question: If a train travels 150 km in 3 hours, what is its speed in m/s?

Options:

Correct Answer: 12.5 m/s

Solution:

Speed in km/h = 150 km / 3 h = 50 km/h. To convert to m/s, multiply by (1000 m / 1 km) * (1 h / 3600 s) = 50 * (1000/3600) = 13.89 m/s.

If a train travels 150 km in 3 hours, what is its speed in m/s?

If a train travels 150 km in 3 hours, what is its speed in m/s?

Step 1: Identify the distance traveled by the train, which is 150 km.
Step 2: Identify the time taken for the journey, which is 3 hours.
Step 3: Calculate the speed in kilometers per hour (km/h) using the formula: Speed = Distance / Time. So, Speed = 150 km / 3 h = 50 km/h.
Step 4: To convert the speed from km/h to meters per second (m/s), use the conversion factor: 1 km/h = (1000 m / 1 km) * (1 h / 3600 s).
Step 5: Multiply the speed in km/h by the conversion factor: 50 km/h * (1000 m / 3600 s).
Step 6: Calculate the result: 50 * (1000 / 3600) = 13.89 m/s.
