Here's the solution ~

`{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:5 \: m \: s {}^( - 1)`

`{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:(5)/(1000) km \: {s}^( - 1)`

`{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:(5)/(1000) * 3600 \: km \: {h}^( - 1)`

`{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \: (5)/(5) * 18 \: km \: h {}^( - 1)`

`{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \: 18 \: km \: h {}^( - 1)`
