transformați: a) 780s=? b) 240 min=?s c) 7h =?min d) 48h =? zile​

Answer 1

$\it 1h=60min\\ \\ 1min=60s\\ \\ 1h=3600s\\ \\ \\ a)\ 780s=\dfrac{780}{60}\ min=13\ min\\ \\ \\ b)\ 240min=240\cdot60s=14400s\\ \\ \\ c)\ 7h=7\cdot60\ min=420\ min$

Answer 2

Explicație pas cu pas:

a)780s= 780/60 min = 13 min

b)240m= 240×60 s = 14 400s

c)7h = 7×60 min = 420 min

d)48h = 48/24 zile= 2 zile

o zi = 24 h

1 h = 60 min

1 min = 60 s
