Final answer:
The car was traveling at a speed of 20 meters per second, calculated by dividing the distance covered (30 meters) by the time taken (1.5 seconds).
Step-by-step explanation:
The question relates to calculating the speed of a car based on information about an object being released from it and the distance covered before the object hits the ground. To find the car's speed, we use the formula for speed, which is speed = distance / time. In this scenario, the car covers 30 meters in 1.5 seconds. Using the formula:
Speed = Distance / Time
Speed = 30 meters / 1.5 seconds
Speed = 20 meters per second
Thus, the car was traveling at 20 meters per second.
