Step-by-step explanation:
We know that,
1 mile = 1609.34 m
We need to find how many meters are present in the 12.45 miles. To find it use unitary method as follows :
12.45 mile = 1609.34 × 12.45
12.45 mile=20036.283 meters
or
![12.45\ mile=2.0036* 10^4\ m](https://img.qammunity.org/2021/formulas/chemistry/high-school/rohyq5u9c91u4v3ik9qj3795pd3rfc6n24.png)
Hence, this is the required solution.
