Final answer:
To convert from meters per second to kilometers per hour, multiply the speed in m/s by 3600 and then divide by 1000. For instance, 30 m/s converts to 108 km/h.
Step-by-step explanation:
Converting Speed from Meters per Second to Kilometers per Hour
To convert a speed from meters per second to kilometers per hour, you can use the following conversion method. Since 1 kilometer equals 1000 meters and 1 hour equals 3600 seconds, you would multiply the speed in meters per second by 3600 to convert seconds to hours and then divide by 1000 to convert meters to kilometers.
Using this method, if you have a speed «1 m/s», you would calculate it as 1 m/s × 3600 s/h / 1000 m/km = 3.6 km/h. Similarly, for a specific example of 30 m/s, the conversion would be 30 m/s × 3600 s/h / 1000 m/km = 108 km/h.
To ensure the conversion is correct, it's helpful to check whether the answer is reasonable considering different scenarios. For instance, if a vehicle traveled 10 km in a third of an hour (20 minutes), it would travel 30 km in a full hour, which aligns with the expectation that 10 km/20 min translates to 30 km/h.
