Answer :

To find [tex]\( 80\% \)[/tex] of 7000 km, you can follow these steps:

1. Understand what percentage means:
- A percentage is a way of expressing a number as a part of a whole, where the whole is 100. So, [tex]\( 80\% \)[/tex] means 80 out of 100 parts.

2. Set up the calculation:
- To find a percentage of a number, you need to multiply the number by the percentage written as a decimal.
- To convert [tex]\( 80\% \)[/tex] to a decimal, divide 80 by 100. So, [tex]\( 80\% \)[/tex] becomes 0.80.

3. Perform the multiplication:
- Multiply 7000 km by 0.80 to find 80% of 7000 km.
[tex]\[
7000 \times 0.80 = 5600
\][/tex]

4. State the result:
- Therefore, [tex]\( 80\% \)[/tex] of 7000 km is 5600 km.

So, the answer is 5600 km.
