An event lasts 4 hours and 20 minutes. How long did the event last in seconds?
daser333 [38]

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,

               4 \times 60=240 \text { minutes }

When the above expressed in seconds,

              240 \times 60=14400 \text { seconds } ------>eq. 1

When 20 minutes expressed in seconds,

              20 \times 60=1200 \text { seconds }------->eq. 2

Adding both eq. 1 and 2, we get

          4 hours and 20 minutes = 14400 + 1200 = 15600 seconds
