The distance from the Sun to the Earth is 149,600,000 km.

[tex]d=149 600 000 \ km = 149 600 000 000 \ m = 1496 \cdot 10^8 \ m \\ v=2 \cdot 10^6 \ \frac{m}{s} \\ \\ \\ t=\frac{d}{v} \\ \\ t=\frac{1496 \cdot 10^8 \ m}{2 \cdot 10^6 \ \frac{m}{s}}=748 \cdot 10^2 \ s =\frac{748 \cdot 10^2 }{36 \cdot 10^2} \ h \approx \underline{\underline{20,78 \ h}}[/tex]
