Answer 1

6.45+1.50=7.95 или 8.35 ч
24-21.30=2.30 ч 
8.35+2.30=10.65 или 11.05 ч

Answer 2

Calculation of Sleep Duration

To calculate the sleep duration of Maxim, we need to find the difference between the time he fell asleep and the time he woke up.

According to the information provided, Anya fell asleep at 9:30 PM and woke up at 6:45 AM.

To find the duration of Maxim's sleep, we need to add 1 hour and 50 minutes to Anya's waking time.

Let's calculate the sleep duration of Maxim:

- Anya's waking time: 6:45 AM - Additional sleep time for Maxim: 1 hour 50 minutes

To find Maxim's waking time, we add 1 hour and 50 minutes to Anya's waking time:

6:45 AM + 1 hour 50 minutes = 8:35 AM

Therefore, Maxim slept until 8:35 AM.

The duration of Maxim's sleep is approximately 10 hours and 5 minutes.

Please note that the calculation assumes that Maxim fell asleep at the same time as Anya and that he did not wake up during the night.
