Answer: The given number is already an integer.
Step-by-step explanation:
Integer is defined as a whole number which is not a fraction. This number can be positive, negative or zero.
Decimal numbers are not considered as integers. They are rounded off to write an integer.
For Example: 4, -2 and 0, all are considered as integers.
We are given a number having value 470,809 miles. The number is already a whole positive number.
Thus, the given number is already an integer.
