Answer 1

1H 25min 20 secunde - 3600 secunde + 1500 + 20 = 5120 secunde
1H 10min - 3600 secunde + 600 = 4200 secunde

Answer 2

1minut=60 secunde
1 ore=60 minute=60×60 secunde=3600 secunde
1H 25 MIN+ 43 min 20 sec + 1h 10 min =?

1H 25 MIN=3600 secunde+25×60=3600+1500=5100 secunde

43 min 20 sec =43×60+20=2580+20=2600 secunde

1h si 10 minute=3600+10×60=3600+600=4200 secunde

1H 25 MIN+ 43 min 20 sec + 1h 10 min =5100 secunde+2600 secunde+4200 secunde=11 900 secunde
