To find the car's average velocity in meters per second, we need to convert the distance traveled from kilometers to meters and divide it by the time taken in seconds.

Given:
Distance traveled = 144 km
Time taken = 2 hours

First, we convert the distance from kilometers to meters:
1 km = 1000 meters
144 km = 144 * 1000 = 144,000 meters

Next, we convert the time from hours to seconds:
1 hour = 3600 seconds
2 hours = 2 * 3600 = 7200 seconds

Finally, we calculate the average velocity:
Average velocity = Distance / Time
Average velocity = 144,000 meters / 7200 seconds
Average velocity = 20 meters per second

Therefore, the car's average velocity is 20 meters per second.
