Daca vantul bate regulat,o ambarcatiune cu panze are viteza de 12 noduri. Calculati distanta in Km parcursa de barca in timp de 1h 40min. (1nod=mila marima / h; 1mila marina =1852m)
v=12 noduri=12 mile marine/h 1 mila marina=1852 m=1,852 km 12 noduri=12 mile marine/h=22,224 km/h v=22,224 km/h=6,17 m/s t=1 h 40 min=3600 s 40 min=6000 s d=? d=v·t d=6,17 m/s·6000 s d=37020 m=37,02 km.
