Here's the solution ~

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:5 \: m \: s {}^{ - 1}$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:\dfrac{5}{1000} km \: {s}^{ - 1}$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:\dfrac{5}{1000} \times 3600 \: km \: {h}^{ - 1}$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: \dfrac{5}{5} \times 18 \: km \: h {}^{ - 1}$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: 18 \: km \: h {}^{ - 1}$
