\(1\) minute \(=\) \(60\) seconds
\(1\) hour \(=\) \(60\) minutes
\(1\) day \(=\) \(24\) hours
Steps to convert hours to seconds:
Step 1: Let us first convert hours to minutes.
Step 2: Then, convert minutes to seconds.
Example:
1. Convert \(1\) hour to seconds.
Solution:
\(1\) hour \(=\) \(60\) minutes
\(=\) \(60\) \(\times\) \(1\) minute
\(=\) \(60\) \(\times\) \(60\) seconds [Since \(1\) minute \(=\) \(60\) seconds]
\(=\) \(3600\) seconds
Therefore, \(1\) hour \(=\) \(3600\) seconds.
2. Convert \(7266\) seconds to hours.
Solution:
Let us do the above procedure in reverse.
First convert seconds to minutes.
\(60\) seconds \(=\) \(1\) minute
\(1\) second \(=\) minute
\(7266\) seconds \(=\) minutes
Now, convert minutes to hours.
\(60\) minutes \(=\) \(1\) hour
\(1\) minute \(=\) hour
minutes \(=\) hour
\(7266\) seconds \(=\) \(2\) hours \(+\) \(66\) seconds
\(=\) \(2\) hours \(+\) \(60\) seconds \(+\) \(6\) seconds
\(=\) \(2\) hours \(+\) \(1\) minute \(+\) \(6\) seconds
Therefore, \(7266\) seconds \(=\) \(2\) hours \(1\) minute \(6\) seconds.
Steps to convert day to seconds:
Step 1: Let us first convert day to hours.
Step 2: Now, convert hours to minutes.
Step 3: Finally, convert minutes to seconds.
Example:
1. Convert \(1\) day to seconds.
Solution:
\(1\) day \(=\) \(24\) hours
\(=\) \(24\) \(\times\) \(1\) hour
\(=\) \(24\) \(\times\) \(60\) minutes [Since \(1\) hour\(=\) \(60\) minutes]
\(=\) \(1440\) minutes
\(=\) \(1440\) \(\times\) \(60\) seconds
\(=\) \(86400\) seconds
Therefore, \(1\) day \(=\) \(86400\) seconds.
