Answer:
A) 2m
B) 8000m
C) 2m
Explanation:
It is important to know that 1 meter = 100 cm = 1000mm = 0.001 km.
We will be using dimensional analysis to solve these problems. To set up dimensional analysis, we need to know the measurement we are converting, and what we are converting to. We also need to know the equivalent of the unit we are converting and what we are converting it to.
If we are converting 900mi to feet, we would set up:
900mi · [tex]\frac{5280ft}{1mi}[/tex] , Notice how the measurement we are converting is being multiplied by a fraction. This fraction is showing the equivalent of 1 mi into feet. Notice how the miles unit is on the bottom, this is necessary so it can cancel out with the miles unit in 900mi to only leave the feet unit.
A) 2000mm
We can use dimensional analysis:
2000mm · [tex]\frac{1 m}{1000mm}[/tex] = 2m
B) 8km
Using the same method:
8km · [tex]\frac{1m}{0.001km}[/tex] = 8000 m
C) 200cm
200cm · [tex]\frac{1m}{100cm}[/tex] = 2m
