Answer:
1 : 1
Explanation:
Step 1) Convert kilometers to meters.
1 kilometers = 1,000 meters
3 kilometers = 3,000 meters
Step 2) Create the ratio.
The ratio is now 3,000 meters to 3,000 meters, which can be written as 3,000 m : 3,000 m.
Step 3) Simplify the ratio.
By dividing by 3,000 on both sides, 3,000 m : 3,000 m simplifies to 1 meter : 1 meter.
