Answer:

\huge\boxed{3\cdot10^8\dfrac{m}{s}=1.08\cdot10^9\dfrac{km}{h}}

Step-by-step explanation:

3\cdot10^8\dfrac{m}{s}\\\\1km=1,000m\to1m=0.001km\\1h=3,600s\to1s=\dfrac{1}{3600}h

therefore

3\cdot10^8\dfrac{m}{s}=3\cdot100,000,000\cdot\dfrac{\frac{1}{1000}km}{\frac{1}{3600}s}=300,000,000\cdot\dfrac{1}{1000}\cdot\dfrac{3600}{1}\dfrac{km}{h}\\\\=\dfrac{300,000,000\cdot3,600}{1,000}\dfrac{km}{h}=300,000\cdot3,600\dfrac{km}{h}=1,080,000,000\dfrac{km}{h}\\\\=1.08\cdot10^9\dfrac{km}{h}
