Celia put hot and cold water into a bathtub. For the first two minutes she added hot water to the bathtub. After two minutes, she added both hot and cold water to the bathtub. The hot water flows at the rate of 2.2 gallons per minute. The cold water flows at the rate of 3.4 gallons per minute. Let t represent the number of minutes Celia put cold water into the bathtub. Which inequality can be used to determine the number of minutes after which the amount of cold water Celia put into the bathtub is greater than the amount of hot water she put into the bathtub?

Answer:

1.2

Step-by-step explanation:

One point two is the answer.

This is about Inequalities.

3.4t > 2.2(t + 2)

  • We are told that;

Rate of flow of hot water = 2.2 gallons/minute

Rate of flow of cold water = 3.4 gallons per minute

Number of minutes that Celia put cold water into the bathtub = t minutes

  • Since she had already put hot water for 2 minutes before putting both hot and cold for another 2 minutes, it means that, for the hot water, the quantity will be; 2.2(t + 2)

  • While for the cold water, the quantity will be 3.4t.

  • Thus, the time for which the number of minutes after which the quantity of cold water put will be greater than the quantity of hot water put will be expressed as;

3.4t > 2.2(t + 2)
