1 minut = 60 secunde
5 min si 8 sec = 5 × 60 + 8 = 300 sec + 8 sec = 308 secunde
10 min si 19 sec = 10 × 60 + 19 = 600 sec + 19 sec = 619 secunde
1 minut = 60 secunde
3 minute = 3 × 60 = 180 secunde
1 min si 10 secunde = 60 sec + 10 sec = 70 secunde
4 min si 15 sec = 4 × 60 = 240 sec + 15 sec = 255 secunde
