Question

exprimati in minute:235 s,3h 17 min,43 min 637 s

Answer 1

235:60=3,91(6) min, 3h17min=3*60+17=180+17=197 min,

43 min 637s=43+637:60=43+10,61(6)=53,61(6) min

Answer 2

un minut are 60 de secunde

235 secunde : 60 secunde = 3,91(6)

235 s - 3 min x 60 s = 235 - 180 s = 55 secunde

235 secunde = 3 minute si 55 secunde

Fara 5 secunde nu sunt 4 minute !

3 h 17 min = 3 x 60 min + 17 min = 180 min + 17 min = 197 minute

o ora are 60 minute

3 h 17 min = 197 minute

43 min 637 s = 43 min + 10 minute + 37 secunde =

= 53 minute 37 secunde
