Steps to Solve
-
Identify the conversion factor To convert kilometers to meters, we need to know that 1 kilometer is equal to 1000 meters.
-
Set up the multiplication We will multiply the distance in kilometers by the conversion factor to get the distance in meters. This gives us the equation: $$ \text{Distance in meters} = \text{Distance in kilometers} \times 1000 $$
-
Perform the calculation Now we substitute the value of 0.4 km into the equation: $$ \text{Distance in meters} = 0.4 , \text{km} \times 1000 = 400 , \text{m} $$
The distance of 0.4 kilometers is equal to 400 meters.
