Number of seconds in 6 hours is equal to the number of minutes in:

Correct option is C

First, calculate the number of seconds in 6 hours.
· 1 hour = 60 minutes
· 1 minute = 60 seconds
· Therefore, 1 hour = 60×60=3600 seconds
For 6 hours: Number of seconds = 6×3600=21600 seconds
Now, let’s calculate the number of minutes in the given options.
· 1 day = 24 hours
· 1 hour = 60 minutes
· Therefore, 1 day = 24×60=1440 minutes
Now, calculate the number of minutes for each option:
· Option (a): 10 days = 10×1440=14400 minutes
· Option (b): 12 days = 12×1440=17280 minutes
· Option (c): 15 days = 15×1440=21600 minutes
· Option (d): 16 days = 16×1440=23040 minutes
The number of seconds in 6 hours is 21600, and the number of minutes in 15 days is also 21600.
Hence, the correct answer is (c) 15 days.
