Zamieniamy prędkość podaną w km/h na prędkość podaną w m/s

$4\frac{\text{km}}{\text{h}}=4\cdot \frac{1\text{km}}{1\text{h}}=4\cdot \frac{1000\text{m}}{3600\text{s}}=\frac{4000\text{m}}{3600\text{s}}=1\frac{4\sout{00}}{36\sout{00}}\frac{\text{km}}{\text{h}}=1\frac{1}{9}\frac{\text{km}}{\text{h}}$  

 

Zamieniamy prędkość podaną w m/s na prędkość podaną w km/h

$3\frac{\text{m}}{\text{s}}=3\cdot \frac{1\text{m}}{1\text{s}}=3\cdot \frac{\frac{1}{1000}\text{km}}{\frac{1}{3600}\text{h}}=3\cdot \left(\frac{1}{1000}\text{km}\cdot \frac{3600}{1}\frac{1}{\text{h}}\right)=3\cdot \left(\frac{36\sout{00}}{10\sout{00}}\frac{\text{km}}{\text{h}}\right)=3\cdot \frac{36}{10}\frac{\text{km}}{\text{h}}=3\cdot 3,6\frac{\text{km}}{\text{h}}=10,8\frac{\text{km}}{\text{h}}$

Zamieniamy prędkość podaną w km/h na prędkość podaną w m/s

$102\frac{\text{km}}{\text{h}}=102\cdot \frac{1\text{km}}{1\text{h}}=102\cdot \frac{1000\text{m}}{3600\text{s}}=\frac{\left(1020\sout{00}\right)\text{m}}{\left(36\sout{00}\right)\text{s}}=\frac{1020\text{m}}{36\text{s}}=28\frac{12}{36}\frac{\text{m}}{\text{s}}=28\frac{1}{3}\frac{\text{m}}{\text{s}}$  

$120\frac{\text{km}}{\text{h}}=120\cdot \frac{1\text{km}}{1\text{h}}=120\cdot \frac{1000\text{m}}{3600\text{s}}=\frac{\left(1200\sout{00}\right)\text{m}}{\left(36\sout{00}\right)\text{s}}=\frac{1200\text{m}}{36\text{s}}=33\frac{12}{36}\frac{\text{m}}{\text{s}}=33\frac{1}{3}\frac{\text{m}}{\text{s}}$
