Duration of Janaki's Mathematics Class
To find the duration of Janaki's mathematics class, we need to calculate the difference between the time she entered the class and the time she came out.
Given information:
- Janaki went to attend her mathematics class at 9:45 a.m.
- She came out at 11:40 a.m.
Calculating the Duration
To calculate the duration, we need to subtract the starting time from the ending time. Let's convert the time into minutes for easier calculation.
Starting time: 9:45 a.m.
- Convert 9:45 a.m. into minutes: 9 * 60 + 45 = 585 minutes
Ending time: 11:40 a.m.
- Convert 11:40 a.m. into minutes: 11 * 60 + 40 = 700 minutes
Now, subtract the starting time from the ending time to find the duration:
Duration = Ending time - Starting time
Duration = 700 minutes - 585 minutes
Duration = 115 minutes
Converting the Duration into Hours and Minutes
Since the duration is in minutes, we need to convert it into hours and minutes format.
1 hour = 60 minutes
Divide the duration by 60 to get the hours:
115 minutes ÷ 60 = 1 hour
The remainder will give us the minutes:
115 minutes % 60 = 55 minutes
Therefore, the duration of Janaki's mathematics class is 1 hour 55 minutes.
