Laura fills a bucket at a rate 6l/min . at the same time sarah empties a bucket holding 30 l of water at a rate of 9l/min . let l repeats the number of liters of water and let repreasent time or min . the system models this situation.
how many min will it take for the buckets to hold equal amounts of water and how much will that be
