Answer:

[tex]7.76\times 10^6\ \text{inches}[/tex]

Step-by-step explanation:

We know that,

[tex]1\ \text{inch}=1.578 \times 10^{-5}\ \text{miles}[/tex]

We need to convert 1225 miles to inches. It can be done as follows :

[tex]1\ \text{mile}=\dfrac{1}{1.578 \times 10^{-5}}\ \text{inches}\\\\1225\ \text{miles}=\dfrac{1225}{1.578 \times 10^{-5}}\ \text{inches}\\\\=7.76\times 10^6\ \text{inches}[/tex]

So, there are [tex]7.76\times 10^6\ \text{inches}[/tex] in 1225 miles.
