A hypothetical old standard for 1 m refers to it as a simple fraction of the distance between the equator and the north-pole what is this fraction ? What would be the practical difficulties in using this as a standard?

Explanation

### Step-by-Step Solution:

1. **Understanding the Definition**: The question refers to a hypothetical old standard for 1 meter defined as a fraction of the distance between the equator and the North Pole. Historically, the distance from the North Pole to the equator was used to define the meter.

2. **Calculating the Distance**: The approximate distance from the North Pole to the equator is about 10,000 kilometers (or 10^7 meters).

3. **Finding the Fraction**: To define 1 meter as a fraction of this distance, we can express it mathematically:
\[
