1. Zamień prędkość: 10 m/s = ........ km/h 5 m/s = ..... km/min 180 km/h = ....... m/s

[latex]10frac{m}{s}=10frac{0,001km}{frac{1}{3600}h}=36frac{km}{h}[/latex] [latex]5frac{m}{s}=5frac{0,001km}{frac{1}{60}min}=0,3frac{km}{min}[/latex] [latex]180frac{km}{h}=180frac{1000m}{3600s}=50frac{m}{s}[/latex]

10 m/s = 10 m/(1/3600 h) = 36 km/h 5 m/s = 5 * 0,001km/(1/60 min) = 0,3 km/min 180 km/h = 180 * 1000/3600 = 180000/3600 = 50 m/s
