4. Rain falling on the most remote point in a given watershed travels over two main paths. First, the rain travels a distance of 520 ft on an average slope of 0.016 f/ft through a path composed of short grass (k = 2.1). The rain then moves into a paved area (k = 20.4) and travels a distance of 35 ft on a slope of 0.001 ft/ft before entering a drainage system. Use the average velocity method to estimate the time of concentration in minutes. %3!
