The total distance which Desirae would run in a week is equal to 21,000 decimeter.
<h3>What is a conversion factor?</h3>
A conversion factor can be defined as a number that is typically used to convert (change) a number in one (1) set of units to another, either by dividing or multiplying.
Generally, an appropriate conversion factor to an equal value must be used when it is necessary to perform any mathematical conversion.
Next, we would convert the unit of distance in kilometer to decimeter as follows:
1 kilometer = 1,000 decimeter
3 kilometer = X decimeter
Cross-multiplying, we have:
X = 3 × 1000
X = 3,000 decimeter.
Note; 1 week is equal to 7 days.
The total distance which Desirae would run in a week is given by:
Total distance = 7 × 3,000
Total distance = 21,000 decimeter.
