Question

9ч 40мин + 40мин =?​

Answer 1

1) 9ч=540 мин

2) 540+40+40=620 мин

3) 620:60 = 10 часов 20 мин

Ответ: 10 часов 20 мин = 620 мин

Answer 2

To add the two time values together, we can simply add the hours and minutes separately:

9 hours + 0 hours = 9 hours 40 minutes + 40 minutes = 80 minutes

Since 1 hour is equal to 60 minutes, we need to convert the 80 minutes into hours and minutes. We can do this by dividing 80 by 60:

80 minutes ÷ 60 = 1 hour and 20 minutes

Now, we have:

9 hours + 1 hour = 10 hours 0 minutes + 20 minutes = 20 minutes

So, the result is 10 hours and 20 minutes.
