This is a unit conversion or dimensional analysis problem.
There are 60min in 1 hour and 60 seconds in 1 min. So you multiple straight across your divison signs and cross out the units that simplify. The number you are left with is the number of seconds in that amount of time.

There are 60 seconds in a minute, so 28 mins = 28*60 seconds = 1680 seconds
There are 60 minutes in an hour, so 5 hrs = 5*60 mins = 300 mins
300 mins = 300*60 seconds = 18000 seconds, so 5 hrs = 18000 seconds
In total we have 5 hrs + 28 mins + 30 seconds = 18000 + 1680 + 30 = 19710 s
You should know that 3600secs=1hr (60secs*60mins)
You should also know that 60 secs=1min
5hrs=3600*5 (=18000secs)
28mins=60*28 (=1680secs)
30secs=30secs
Add all the seconds together:
18000 + 1680 + 30 = 19710 secs
19710seconds
