Пошаговое объяснение:

1 час = 60 минут

​1ч - 15 мин  = 60 мин - 15 мин = 45 мин

2ч - 20 мин  = 1 час 60 мин - 20 мин = 1 ч 40 мин

З ч — 1ч 5 мин​ = 2 ч 60 мин - 1ч 5 мин = 1 ч 55 мин

Answer 3

To find the value of Z, we can convert the given times to a common unit, such as minutes, and then solve for Z.

1 hour is equal to 60 minutes, so 1 hour and 15 minutes is 60 + 15 = 75 minutes. 2 hours is equal to 120 minutes, so 2 hours and 20 minutes is 120 + 20 = 140 minutes.

Now, let's set up the equation using the given information:

Z hours is equal to 1 hour and 5 minutes, which is 60 + 5 = 65 minutes.

Z * 60 minutes = 65 minutes

Now, we can solve for Z by dividing both sides of the equation by 60:

Z = 65 minutes / 60 minutes Z = 1.0833

Therefore, Z is approximately equal to 1.0833.
