Answer 2

Speed in the SI System

In the SI (International System of Units), speed is typically measured in meters per second (m/s). However, to convert a speed of 18 km/h to the SI unit of meters per second, you can use the following conversion:

1. Convert 18 km/h to m/s: - To convert kilometers per hour to meters per second, you can use the conversion factor: 1 km/h = 0.27778 m/s. - Therefore, 18 km/h is equal to 5 m/s.

This conversion can be calculated using the following formula: ``` speed_in_mps = speed_in_kmph * (1000 meters / 1 kilometer) * (1 hour / 3600 seconds) ``` Substituting the value of 18 km/h into the formula: ``` speed_in_mps = 18 * (1000 / 3600) ≈ 5 m/s ```

The speed of 18 km/h is approximately equal to 5 m/s.
