Answer:
7.44
Step-by-step explanation:
Given:
Steel pipe weighs = 5 pounds per foot.
Question asked:
How much does it weigh in kilograms per meter ?
Solution:
We will convert foot into meter and pound into kilograms.
1 foot = 0.305 meters
1 pound = 0.454 kilograms
5 pounds = [tex]5\times0.454=2.27\ kilograms[/tex]
By using unitary method:
0.305 meters of steel pipe weighs = 2.27 kilograms.
1 meter of steel pipe weighs = [tex]\frac{2.27}{0.305} =7.44[/tex]
Therefore, it weigh in kilograms per meter is 7.44
