Beyond the Answer
To find out how many gallons of water can flow in one minute, you can divide the total gallons by the total minutes: 350 gallons ÷ 25 minutes = 14 gallons per minute. So, the hose flows at a rate of 14 gallons every minute! For the equation in slope-intercept form (y = mx + b), let's define y as the total gallons, x as the time in minutes, m as the rate of flow (14 gallons/minute), and b as the initial amount (0 gallons at 0 minutes). The equation is y = 14x + 0 or simply y = 14x. To find out how many gallons can flow in 60 minutes, plug x = 60 into your equation: y = 14(60) = 840 gallons. So, the hose can flow 840 gallons in 60 minutes!
