Understanding the Reading Time
Radha read for 3 hours and 50 minutes today. To convert this time into seconds, we need to break it down into hours and minutes, and then convert everything to seconds.
Step 1: Convert Hours to Seconds
- 1 hour = 3600 seconds
- Radha read for 3 hours, so:
- 3 hours = 3 × 3600 = 10800 seconds
Step 2: Convert Minutes to Seconds
- 1 minute = 60 seconds
- Radha read for 50 minutes, so:
- 50 minutes = 50 × 60 = 3000 seconds
Step 3: Add the Seconds Together
- Now, combine the seconds from hours and minutes:
- Total seconds = Seconds from hours + Seconds from minutes
- Total seconds = 10800 seconds + 3000 seconds = 13800 seconds
Conclusion
Radha read the book for a total of 13800 seconds today. Therefore, the correct answer is option 'A'.
