Question

Cu ce viteza se deplaseaza un mobil care oarcurge 70 km in 45 min v=m supra s.Va roog trebuie facut cu datele problemei etc ca in clasa

Answer 1

$v = \frac{d}{t}$
70 km= 70.000 m
45 minute = 2.700 secunde
$v = \frac{70.000}{2.700} = \frac{700}{27} = 25.92 \:$
25,92 m/s

Answer 2

d=70 km=70000 m

t=45 min=2700sec

stim ca v=/frac{d}{t}

v=70000m:2700sec=aproximativ 26m/s
