Question

Convert 8h 50min 20sec into seconds?

Answer 1

Answer:

Given : 8 hour 50 min 20 sec

we know that  1 hour = 60 min, 1 min = 60 sec

then 8 hour 50 min and 20 sec = 8*3600+50*60+20 = 28800+3000+20

                                                                                        = 31820 secs
