4 times, non-overlapping intervals.
15 hours = 54,000 seconds.
We already know how many seconds there are in 24 seconds (24), so all we need to calculate is the "15 minutes" part. 1 minute = 60 seconds 15 minutes = (15 x 60) = 900 seconds. Add the extra 24 seconds, total = 924 seconds.
There are 60 seconds in one minute. Therefore, 15 seconds is equal to 15/60 = 0.25 minutes.
1 minute = 60 seconds so 1 minute 15 seconds = 60+15 = 75 seconds.
