Time adding

Add and write the result again as hours, minutes, seconds:

2hodiny45min15s + 1h20m50s =

Correct result:

h =  4
m =  6
s =  5


t1=2 3600+45 60+15=9915 t2=1 3600+20 60+50=4850 t=t1+t2=9915+4850=14765 h1=t/3600=14765/3600=29537204.1014 h=h1=4.1014=4
t3=t3600 h=147653600 4=365 m1=t3/60=365/60=73126.0833 m=m1=6.0833=6
s=t360 m=36560 6=5s=t_{3} - 60 \cdot \ m=365 - 60 \cdot \ 6=5
