1m/s=3,6km/h a) 7m/s * 3,6= 25,2km/h b)30m/s*3,6=108km/h c)7.9*10^3m/s*3,6=28440km/h d)2,19*10^6m/s*3,6=7884000km/h

a) V=7m/s = 7*36/10 km/h = 25,2 km/h b) V=30m/s = 30*36/10 km/h = 108 km/h c) V=7,9*10³ m/s = 7,9*10³*36/10 km/h = 28,44*10³ km/h d) V=2,19*10⁶ m/s = 2,19*10⁶*36/10km/h = 7,884*10⁶ km/h
