PILNE!! NA JUTRO Wyraź w km/h : V= 20 cm/s v= 200 m/s V= 300 m/s v = 10 mm/s wyraź w m/s v= 5000 km/h v= 50 km/h V= 2 km/h v= 15 km/h

v = 20cm/s = 20 x (0,00001m : 1/3600h) = 20 x 0,036km/h = 0,72km/h v = 200m/s = 200 x (0,001m : 1/3600h) = 200 x 3,6km/h = 720km/h v = 300m/s x (0,001km : 1/3600h) = 300 x 3,6km/h = 1080km/h v = 10mm/s = 10 x (0,000001km : 1/3600h) = 10 x 0,0036km/h = 0,036km/h v = 5000km/h = 5000 x 1000m/3600s ≈ 1389m/s v = 50km/h = 50 x 1000m/3600s ≈ 14m/s v = 2km/h = 2 x 1000m/3600s ≈ 0,6km/h v = 15km/h = 15 x 1000m/3600s ≈4,17m/s
