اذا كانت سرعه سياره ٧٢ كم /س فهذا يعني ان سرعتها تساوي كام م/ث

If a car is moving at a speed of 72 km/h, this means its speed is equal to how many m/s: Since 1 kilometer is equal to 1000 meters and 1 hour is equal to 3600 seconds, we can convert the speed from km/h to m/s by multiplying 72 km/h by (1000/3600) to get 20 m/s.
