Answer:
The pipe lengths are 50 inches and 100 inches.
Explanation:
If we refer to the length of the shorter piece as x, then we can say the length of the larger piece is 2x. We are also told that the pipe length is 150 inches, so we can say:
x + 2x = 150
3x = 150
x = 150/3
x = 50
So the pipe lengths are 50 and 100 inches respectively.
