Question

To
function properly, a rainwater outflow pipe must drop exactly 1 inch for every 25 Inches of horizontal distance. A 40 feet long rainwater pipe
runs under the edge of a roof. What is the vertical distance, in inches, the pipe must drop between its ends? Round your answer to the nearest
tenth.

Answer 1

Given, length of pipe = 40ft × 12 = 480 inches

Required horizontal distance = 25 inches

Now it's asked the vertical distance of pipe if every 25 inches of horizontal distance drop exactly at 1 inch.

So, Vertical distance = 480/25 = 19.2 inches

Hope this helps :)
