If one section of hose is 50 feet, how long is 15 sections of hose?

To determine the total length of 15 sections of hose, you need to multiply the length of one section by the total number of sections. Given that one section of hose measures 50 feet, the calculation would be:

Total length = Length of one section × Number of sections
Total length = 50 feet × 15 sections
Total length = 750 feet.

This calculation confirms that the correct answer is 750 feet, as you correctly identified. Understanding this multiplication of the length per section by the number of sections is crucial, especially in firefighting contexts where knowing the total length of hoses can impact water delivery and system efficiency.
