If one section of hose is 50 feet, how long would 9 sections be?

To find the total length of 9 sections of hose when each section is 50 feet long, you perform a straightforward multiplication. Each section adds another 50 feet, so you multiply the number of sections by the length of each section:

9 sections × 50 feet/section = 450 feet.

This calculation shows that the complete length when you have 9 sections of hose, each being 50 feet, results in a total of 450 feet. The reasoning hinges on understanding basic multiplication of whole numbers and applying it to a real-world scenario, such as measuring the length of hose. Therefore, the conclusion that the total length of the hose is 450 feet is clearly justified by the arithmetic used in the problem.
