Now, Let's Convert it :

[tex] \\ \longrightarrow \qquad \sf \: 54km / hr \\ [/tex]

[tex]\\ \longrightarrow \qquad \sf \: \frac{54 \times 1km}{1hr} \\ [/tex]

[tex]\\ \longrightarrow \qquad \sf \: \frac{54 \times 1000m}{3600s} \\ [/tex]

[tex]\\ \longrightarrow \qquad \sf \: \frac{54000 m}{3600s} \\ [/tex]

[tex]\\ \longrightarrow \qquad \sf \: \frac{540\cancel{0 }\cancel{0} m}{36 \cancel{0 }\cancel{0}s} \\ [/tex]

[tex]\\ \longrightarrow \qquad \sf \: \frac{540 m}{36s} \\ [/tex]
