Question

It takes 12 minutes to fill an entire bathtub using both the cold and hot water. If just the cold water is used, it takes 18 minutes to fill the bathtub. How long would it take to fill the bathtub if just the hot water were used? The equation can be used to solve for the rate, r, for the hot water alone to fill the bathtub. The hot water can fill of the tub in 1 minute. It would take minutes for the hot water to fill the bathtub.
