GPT 3.5
We know that 1 km is equal to 1000 meters and 1 hour is equal to 3600 seconds.
Therefore, to find the speed in meters per second, we first need to convert the distance from kilometers to meters:
72 km = 72 * 1000 = 72000 meters
Now, we need to convert the time from hours to seconds:
1 hour = 3600 seconds
Now we can calculate the speed in meters per second:
Speed = Distance / Time
Speed = 72000 meters / 3600 seconds
Speed = 20 meters per second
Therefore, the car's speed is 20 meters per second.
Therefore, to find the speed in meters per second, we first need to convert the distance from kilometers to meters:
72 km = 72 * 1000 = 72000 meters
Now, we need to convert the time from hours to seconds:
