2 часа 17 минут = 2 целых 17/60 ч
56 секунд = 56/3600 часа

23 часа = 23/24 суток
39 минут = 39/1440 суток = 13/480 суток

Answer 2

Conversion of Time Units

To convert the given time values into hours, we need to add up the hours, minutes, and seconds separately.

The given time values are: - 9 minutes - 2 hours 17 minutes - 56 seconds

To convert minutes to hours, we divide the number of minutes by 60. Similarly, to convert seconds to hours, we divide the number of seconds by 3600.

Let's calculate the total time in hours:

1. Convert 9 minutes to hours: - 9 minutes ÷ 60 = 0.15 hours.

2. Convert 2 hours 17 minutes to hours: - 2 hours + 17 minutes ÷ 60 = 2.28333333 hours (rounded to 8 decimal places).

3. Convert 56 seconds to hours: - 56 seconds ÷ 3600 = 0.01555556 hours (rounded to 8 decimal places).

Now, let's add up the converted time values:

0.15 hours + 2.28333333 hours + 0.01555556 hours = 2.44888889 hours (rounded to 8 decimal places).

Therefore, the given time values of 9 minutes, 2 hours 17 minutes, and 56 seconds are equivalent to approximately 2.44888889 hours.
