a) 0,003mm/s = 0,003 * 1/1000 / 1 m/s = 0,003 * 1/1000m/s = = 3/1000 * 1/1000 = 3/1000000 = 0,000003m/s b) 360km/h = 360 * 1000/3600m/s = 360 * 10/36m/s = 100m/s ============================================================ a) 10cm/s = 10 * 1/10000 / 1/3600 km/h = 10 * 1/10000km/h  * 3600km/h = 1/1000 * 3600km/h = 0,36km/h 30m/s = 30 * 1/1000 / 1/3600km/h = 30 * 1/1000 * 3600km/h = = 30 * 18/5 km/h = 108km/h
