**Problem Analysis:**
To find the distance moved by the car, we need to subtract the initial reading on the odometer from the final reading. The speed of the car can be calculated by dividing the distance moved by the time taken.
**Given:**
- Initial odometer reading = 57321.0 km
- Final odometer reading = 57336.0 km
- Time taken = 20 minutes (from 8:30 AM to 8:50 AM)
**Distance moved by the car:**
The distance moved by the car can be calculated by subtracting the initial odometer reading from the final odometer reading.
Distance moved = Final odometer reading - Initial odometer reading
Distance moved = 57336.0 km - 57321.0 km
Distance moved = 15.0 km
Therefore, the car moved a distance of 15.0 km.
**Speed of the car:**
The speed of the car can be calculated by dividing the distance moved by the time taken.
Speed = Distance moved / Time taken
Speed = 15.0 km / 20 min
To convert the speed to km/h, we need to convert the time from minutes to hours.
1 hour = 60 minutes
So, 20 minutes = 20/60 = 1/3 hours
Speed = 15.0 km / (1/3) hours
Speed = 15.0 km * 3
Speed = 45.0 km/h
Therefore, the speed of the car during this time period is 45.0 km/h.
**Conclusion:**
The car moved a distance of 15.0 km and the speed of the car during this time period was 45.0 km/h.
