A Correct answer
Explanation

Distance = 57336.0 - 57321.0 = 15 km. Time = 20 minutes. Speed = 15 km / 20 min = 0.75 km/min.

AI explanation

The total distance moved by the car is the difference in odometer readings, which is 57336.0 - 57321.0 = 15 km. The total time elapsed is from 08:30 AM to 08:50 AM, which is 20 minutes. Using the formula speed = distance/time, the speed of the car is 15/20 km/min, which equals 0.75 km/min.
