Answer 1

`7.76* 10^6\ \text{inches}`

Explanation:

We know that,

`1\ \text{inch}=1.578 * 10^(-5)\ \text{miles}`

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

`1\ \text{mile}=(1)/(1.578 * 10^(-5))\ \text{inches}\\\\1225\ \text{miles}=(1225)/(1.578 * 10^(-5))\ \text{inches}\\\\=7.76* 10^6\ \text{inches}`

So, there are
`7.76* 10^6\ \text{inches}` in 1225 miles.
