The amount of water used is directly proportional to the amount of time that the shower is in use. So, the ratio of water used to time is constant.Let's call this constant k. Then, we have:water used = k * timeWe can find the value of k by using the given information:13.6 gallons = k * 17 minutesk = 13.6 gallons / 17 minutesk = 0.8 gallons / minuteNow, we can use this value of k to find the amount of water used in a shower lasting 5 minutes:water used = k * timewater used = 0.8 gallons / minute * 5 minuteswater used = 4 gallonsTherefore, the amount of water used in a shower lasting 5 minutes is 4 gallons.
