Question

Transformati in secumde: a) 25 mim b) 2h c) 1h 12min d) 55min e) 3h 15min f) 4h 50min.
As vrea si transformare nu doar rezultatul. Multumesc!

Answer 1

25 min = 1500 sec
2 h = 7200 sec
1h 12 min = 4320 sec
55 min = 3300 sec
3h 15 min = 11700 sec
4h 50 min = 17400 sec

Answer 2

1 min=60 sec si 1h=3600sec
25 min=25x60=1500 sec
2h=3600x2=7200 sec
1h 12 min=3600 sec+720 sec=4320 sec
55 min=55x60=3300 sec
3h 15 min=10800 sec+900 sec=11700 sec
4h 50 min=14400 sec+3000 sec=17400 sec
