Answer 2

Answer:

30 km/h = 12.5 m/s

Step-by-step explanation:

1km = 1000 m

1 h = 3600 s

$\frac{1 \: km}{1 \: h} \\ = \frac{1000 \: m}{3600 \: s} \\ = \frac{5}{18} {m \: s}^{ - 1} \\ 30 \: {km \: h}^{ - 1} = 30 \times \frac{5}{18} {m \: s}^{ - 1} \\ \: \: = \frac{25}{2} {m \: s}^{ - 1} \\ = 12.5 {m \: s}^{ - 1}$
