Question

20мин 30сек + 25сек = 2мин 30сек - 1мин = 5м 75см - 3см= 6м 20см + 75см =

Answer 1

20мин 30сек + 25сек =1255СЕК

2мин 30сек - 1мин =210СЕК

5м 75см - 3см=572СМ

6м 20см + 75см =695СМ

Answer 2

Let's break this down step by step:

1. 20 minutes 30 seconds + 25 seconds: 20 minutes + 0 minutes (since there are no additional minutes to add) = 20 minutes 30 seconds + 25 seconds = 55 seconds

2. 2 minutes 30 seconds - 1 minute: 2 minutes - 1 minute = 1 minute 30 seconds - 0 seconds (since there are no additional seconds) = 30 seconds

3. 5 meters 75 centimeters - 3 centimeters: 5 meters - 0 meters (since there are no additional meters to subtract) = 5 meters 75 centimeters - 3 centimeters = 72 centimeters

4. 6 meters 20 centimeters + 75 centimeters: 6 meters + 0 meters (since there are no additional meters to add) = 6 meters 20 centimeters + 75 centimeters = 95 centimeters

Now, we can add up the results:

1. 20 minutes + 1 minute = 21 minutes
2. 55 seconds + 30 seconds = 85 seconds
3. 5 meters + 0 meters = 5 meters
4. 72 centimeters + 95 centimeters = 167 centimeters

So, the final result is: 21 minutes 85 seconds and 5 meters 167 centimeters.
