Q. Fred's basement is flooded. The basement floor is 3.4 meters below ground level. The top of the water is 2.2 meters below ground level.The following equation describes this situation.−3.4+1.2=−2.2What does 1.2 tell us?Choose 1 answer:(A) The top of the water is 1.2 meters below ground level.(B) The top of the water is 1.2 meters above ground level.(C) The water is 1.2 meters deep.
Interpreting the equation: We are given that the basement floor is 3.4 meters below ground level and the top of the water is 2.2 meters below ground level. The equation provided is −3.4+1.2=−2.2. To understand what 1.2 represents, we need to interpret the equation in the context of the problem.
Understanding −3.4: The equation starts with −3.4, which represents the basement floor being 3.4 meters below ground level. We then add 1.2 to this value. The result of this addition is −2.2, which represents the top of the water being 2.2 meters below ground level.
Calculating the depth of water: The value of 1.2 is the difference between the basement floor level and the top of the water level. This means that 1.2 meters is the depth of the water in the basement since it is the amount that needs to be added to the basement floor level (−3.4 meters) to reach the top of the water level (−2.2 meters).
