Russian Inventors Father and Son Cherepanov and Their Steam Locomotive

Father and son Cherepanov were remarkable self-taught Russian inventors who built the first steam locomotive in 1834. This locomotive was able to travel 500 meters in 2 minutes. Let's calculate the speed of this steam locomotive in meters per minute and kilometers per hour.

To calculate the speed, we can use the formula:

Speed = Distance / Time

Given that the distance traveled is 500 meters and the time taken is 2 minutes, we can substitute these values into the formula to find the speed.

Speed = 500 meters / 2 minutes

To convert the speed from meters per minute to kilometers per hour, we need to consider the conversion factor:

1 kilometer = 1000 meters 1 hour = 60 minutes

Let's calculate the speed in meters per minute and then convert it to kilometers per hour.

Calculation:

Speed = 500 meters / 2 minutes

Speed = 250 meters per minute

To convert meters per minute to kilometers per hour, we can use the following conversion factor:

1 kilometer = 1000 meters 1 hour = 60 minutes

Speed (in kilometers per hour) = (250 meters per minute * 60 minutes) / 1000 meters

Speed (in kilometers per hour) = 15 kilometers per hour

Therefore, the speed of the Cherepanovs' steam locomotive was 250 meters per minute and 15 kilometers per hour.
