Calculations

The calculations can be written as follows: - 18 hours 36 minutes - 9 hours - 18 hours 36 minutes - 9 minutes - 12 kilometers 65 meters 20 meters + 20 minutes 30 seconds 25 seconds - 2 minutes 30 seconds - 1 minute - 6 meters 20 centimeters 75 centimeters

Let's solve these step by step.

1. 18 hours 36 minutes - 9 hours - 18 hours 36 minutes - 9 hours = 9 hours 36 minutes - Result: 9 hours 36 minutes

2. 18 hours 36 minutes - 9 minutes - 18 hours 36 minutes - 9 minutes = 18 hours 27 minutes - Result: 18 hours 27 minutes

3. 12 kilometers 65 meters 20 meters + 20 minutes 30 seconds 25 seconds - 12 kilometers 65 meters 20 meters + 20 minutes 30 seconds 25 seconds = 12 kilometers 65 meters 40 meters + 20 minutes 55 seconds - Result: 12 kilometers 65 meters 40 meters + 20 minutes 55 seconds

4. 2 minutes 30 seconds - 1 minute - 2 minutes 30 seconds - 1 minute = 1 minute 30 seconds - Result: 1 minute 30 seconds

5. 6 meters 20 centimeters 75 centimeters - 6 meters 20 centimeters 75 centimeters = 6 meters 21 centimeters - Result: 6 meters 21 centimeters

So, the results of the calculations are: - 9 hours 36 minutes - 18 hours 27 minutes - 12 kilometers 65 meters 40 meters + 20 minutes 55 seconds - 1 minute 30 seconds - 6 meters 21 centimeters
