Answer:

speed \:  \:  = 54 \:  \: km {h}^{ - 1 }  \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   = 54 \times 1000 \:  \: m {h}^{ - 1}  \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   =   \frac{54 \times 10 \cancel{00}}{36 \cancel{00}}  \:  \: m {s}^{ - 1 }  \\  \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   =  \frac{ \cancel{54}^{ \:  \:  \: 6} \times 10}{{ \cancel{36} } ^{ \:  \:  \:  4 }  }\:  \: m {s}^{ - 1}  \:\:\:\:\:[divided \:by\: 9\:]\\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   =  \frac{6 \times 10}{4} \:  \: m {s}^{ - 1}   \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   =  \frac{60}{4} \:  \:  \: m {s}^{ - 1}   \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   = 15 \:  \: m {s}^{ - 1}
