3 przykłady na szybko. 50km/h zamień na m/s 15km/h zamień na m/min 45m/min zamień  na cm/s Z góry dzięki.:)

50 km/h = 50 * 1000m/3600s = 13,8 m/s 15 km/h = 15 * 1000m/60s = 250 m/min 45 m/min = 45 * 100cm/60s = 75 cm/s

[latex]50*frac{1000m}{3600s}[/latex]=5000m/360s=13,(8)m/s [latex]15*frac{1000m}{60min}[/latex]=15000m/60min=250m/min [latex]45*frac{100cm}{60s} [/latex]=4500cm/60s=75cm/s
