Va rog ajutati-ma dau coroana si multumesc!!​

viteza = distanta / timp

1.  v = 120 km/h

    t = 1,5 h

distanta = viteza x timp = 120 km/h x 1,5 h =  180 km

2. d = 3000 m = 3 km

  v = 170 km/h

t = distanta / viteza = 3 km / 170 km/h = 0,0176 ore

0,175 ore  x 3600 s / ora =  63,5 secunde ( 1 minut si 3,5 secunde )

v=120km/h

t=1,5h

d=?

v=d/t

d=vxt

d=120km/h x 1,5h

d=180km

d=3000m=3km

v=170km/h

t=?

v=d/t

t=d/v

t=3km/170km/h

t=0,017h

Succes!
