Answer 2

Answer:

Option B ✓

$\sf{ \dfrac{5}{18} \: m/s}$

Step-by-step explanation:

1 km = 1000 m

1 h = 60 × 60 s = 3600 s

Let's change the unit now !

$\sf{1 \: km/h=1 \: \dfrac{km}{h} }$

$= \sf{1 \times \dfrac{1000 \: m}{3600 \: s} }$

$\sf{ = \dfrac{5 \: m}{18 \: s} }$

$\sf{= \dfrac{5}{18} \: m/s}$
