Here: First, you multiply the hours into minutes, so 60 minute is 1 hour, so 5 x 60 (Or 60 x 5) = 300, then since those are minutes, add the 30 minutes you have, 300 + 30 = 330, then multiply the minutes into seconds, which would be 330 x 60 (Or 60 x 330) = 19800 since there are 60 seconds in a minute, so your answer would be 19800 seconds.
