In cat timp va parcurge un melc o distanta d=10m , daca viteza lui este v=2 cm/s

2
t=d*v v=0.02 m/s t=10/0,02=500s ( daca nu ma insel asa este corect )
2cm = 0,002 m/s ; V=d/t=>t=d/v=5000s
t=dxv v=0,02 m/s t=10/0 ,2=500s
ssau cred ca 2cm =0,02 m / s si v=d/t = =d/v=5000s
V=d/t=>t=d/v=5000s

Cred k in 500s . 100cm-1m = 50s-10 = 500
