Final answer:
The rate in meters per second for a car traveling at 70 km/h is approximately 19.4446 m/s, which is calculated by multiplying the speed in km/h by the conversion factor of 0.27778 m/s per km/h.
Step-by-step explanation:
The rate in meters per second for a car traveling at 70 km/h is approximately 19.4446 m/s, which is calculated by multiplying the speed in km/h by the conversion factor of 0.27778 m/s per km/h.To convert a car's speed from kilometers per hour (km/h) to meters per second (m/s), we use the conversion factor that 1 km/h is equal to 0.27778 m/s. For a car traveling at 70 km/h, we multiply this speed by the conversion factor:
Speed in m/s = 70 km/h × 0.27778 m/s per km/h
Speed in m/s = 19.4446 m/s
Therefore, the rate in meters per second for a car traveling at 70 km/h is approximately 19.4446 m/s.
