A cylindrical container has a height of 24 inches. Currently, the container is filled with water to a height of 18 inches. A leaky faucet drips into the container, causing the height of the water in the container to increase by 2 inches per hour. The equation below can be used to find t, the number of hours it would take to fill the container.18 + ?t = 24What number should be the coefficient of t?
The water starts at 18 inches and rises by 2 inches each hour, so after t hours its height is 18 + 2t. Setting that equal to the container’s full height gives 18 + 2t = 24. The coefficient of t is 2, meaning the water rises 2 inches per hour.
