Answer:
[tex]3\times 10^5\ \dfrac{km}{s}=6.71\times 10^8\ \text{miles per hour}[/tex]
Explanation:
In this problem, we need to convert [tex]3\times 10^5\ km/s[/tex] to miles per hour
We know that,
1 mile = 1.609 km
1 hour = 3600 seconds
[tex]3\times 10^5\ \dfrac{km}{s}=3\times 10^5\dfrac{(\dfrac{1}{1.609}\ \text{miles})}{\dfrac{1}{3600}\ \text{hour}}\\\\=6.71\times 10^8\ \text{miles per hour}[/tex]
Hence, [tex]3\times 10^5\ \dfrac{km}{s}=6.71\times 10^8\ \text{miles per hour}[/tex]
