| When solving the problem, we need a path formula:

S = v * t, where S is the distance traveled, v is the speed on the way, t is the travel time.

Since we know the distance and time, and we need to calculate the speed, we express the speed from this formula:

v = S / t.

So, let’s calculate the speed with which the car was traveling, if it is known that it covered a distance of 30 km in 2.5 hours.

v = 30 / 2.5 = 12 km per hour.

Answer: The speed of the car is 12 km per hour.
