The odometer of a car reads 57321.0 km when the clock shows the time 08:30 AM. What is the distance moved by the car, if at 08:50 AM, the odometer reading has changed to 57336.0 km? Calculate the speed of the car in km/min during this time. Express the speed in km/h also.

To find the distance moved by the car between 8:30 AM and 8:50 AM, subtract the initial odometer reading from the final odometer reading:

Initial odometer reading = 57321.0 km
Final odometer reading = 57336.0 km

Distance moved = Final odometer reading – Initial odometer reading
Distance moved = 57336.0 km – 57321.0 km
Distance moved = 15.0 km

Therefore, the distance moved by the car between 8:30 AM and 8:50 AM is 15.0 kilometers.

To calculate the time taken:
Time taken = Time at 8:50 AM – Time at 8:30 AM
Time taken = 20 minutes (since 8:50 AM – 8:30 AM = 20 minutes)

Now, to calculate the speed of the car in km/min:
Speed = Distance / Time
Speed = 15.0 km / 20 min
Speed = 0.75 km/min

To express the speed in km/h:
Since 1 hour = 60 minutes,
Speed in km/h = Speed in km/min * 60
Speed in km/h = 0.75 km/min * 60
Speed in km/h = 45 km/h

Therefore, the speed of the car during this time period is 0.75 kilometers per minute or 45 kilometers per hour.
