Question

Question 45 A length of pipe that weighs 45 pounds is cut into two pieces. One of the pieces is 3 feet long and weighs 18 pounds. In feet, what is the length of the other piece?

Answer 1

Answer: 4.5 pounds.

Explanation:

Given : Weight of original pipe =45 pounds

Weight of first piece = 18 pounds

Then, Weight of other piece = 45- 18 = 27 pounds

Length of first piece = 3 feet

Let x be the length of other piece.

As length is directly proportional to weight.

Then,
`(x)/(27)=(3)/(18)`

`\Rightarrow\ (x)/(27)=(1)/(6)\\\\\Rightarrow\ x=(1)/(6)*27 =4.5`

Hence, the he length of the other piece = 4.5 pounds.
