Przelicz: 1. 18 km/h = m/s 2. 72 km/h = m/s 3.1 km/h = m/s 4. 3,6 m/s = km/h 5. 90 m/s = km/h 6.5m/s = km/h kochani to na ocene pomozecie ?

1. 18km/h=18000m:3600s=5m/s 2. 72km/h=72000m:3600s=20m/s 3. 1km/h=1000m:3600s=0,27778m/s 4. 3,6m/s*3600s=12960m=12,96km/h 5. 90m/s*3600s=32400m=324km/h 6. 5m/s*3600s=18000m=18km/h
