The event last in 15,600 seconds.
Answer: Option B
<u>Explanation:</u>
We know that there is 60 seconds in one minute i.e., 1 minute = 60 seconds
There is 60 minutes in one hour. i.e., 60 minutes = 1 hour.
Given : An event lasts 4 hours and 20 minutes
4 hours contains 240 minutes,

When the above expressed in seconds,
------>eq. 1
When 20 minutes expressed in seconds,
------->eq. 2
Adding both eq. 1 and 2, we get
4 hours and 20 minutes = 14400 + 1200 = 15600 seconds
