How many seconds are in a stopwatch showing 4 hours 3 minutes and 10 seconds?

4 hrs 3 minutes 10 seconds

1 hr = 60 minutes...so 4 hrs = (4 * 60) = 240 minutes
so we now have 240 + the 3 minutes = 243 minutes and 10 seconds

1 minute = 60 secondsso 243 minutes = (243 * 60) = 14580 seconds

so we end up with 14580 seconds + 10 seconds = 14590 seconds <==
