‘please answer both 4. Rohit watched television for 1 h 55 min. For how many seconds did he watch the television?’
The Correct Answer and Explanation is:
To find the total time Rohit spent watching television in seconds, we need to convert 1 hour and 55 minutes into seconds.
- Start with the hours:
1 hour = 60 minutes
Therefore, 1 hour = 60 minutes. - Add the 55 minutes:
Now, we have 60 minutes + 55 minutes = 115 minutes in total. - Convert the total minutes into seconds:
Since there are 60 seconds in a minute, we multiply the total minutes (115) by 60: 115 minutes×60 seconds/minute=6900 seconds115 \, \text{minutes} \times 60 \, \text{seconds/minute} = 6900 \, \text{seconds}115minutes×60seconds/minute=6900seconds
Thus, Rohit watched television for 6900 seconds.
Explanation:
- Time can be expressed in various units (hours, minutes, seconds). To find the total time in a single unit (seconds in this case), we first break down the time into minutes, then convert minutes into seconds.
- Step 1 converts hours into minutes, which is the standard approach when dealing with hours.
- Step 2 adds the remaining minutes to ensure the total minutes are correct.
- Step 3 converts the total minutes into seconds by multiplying by 60, as there are 60 seconds in a minute.
So, the final result is that Rohit spent 6900 seconds watching television.
