To determine the weight of 100 feet of pipe when 300 feet weighs 450 pounds, one can first calculate the weight per foot of the pipe. This is done by dividing the total weight of the 300 feet by the total length:

450 pounds divided by 300 feet equals 1.5 pounds per foot.

Now, to find the weight of 100 feet, simply multiply the weight per foot by the number of feet:

1.5 pounds per foot multiplied by 100 feet equals 150 pounds.

This calculation shows that the correct answer is indeed 150 pounds, which corresponds with the answer option selected. Understanding this relationship allows for easy calculations of weight based on varying lengths of similar material.
