Final answer:
The speed limit sign of 100 indicates the maximum speed you are allowed to drive on that road, translating to roughly 100 km/h, 27.778 m/s, or 62.14 mi/h.
Step-by-step explanation:
The speed limit sign with the number 100 tells you the maximum permissible speed at which you can travel on that stretch of road. It does not represent the minimum speed or the recommended speed. The limit is generally provided in kilometers per hour (km/h) and is the top speed that vehicles are legally allowed to travel in a given area under ideal conditions.
Under the system of units used in physics, particularly SI (International System of Units), speed can also be expressed in meters per second (m/s). For those more familiar with the Imperial system, speed is often thought of in miles per hour (mi/h). To convert 100 km/h to m/s, you would use the conversion factor 1 km/h = 0.27778 m/s. Therefore, 100 km/h is approximately 27.778 m/s. Similarly, to convert to miles per hour, knowing that 1 mile = 1.609 km helps in understanding that 100 km/h is roughly equivalent to 62.14 mi/h.
