A parking garage has floors above and below ground level. For a scavenger hunt, galas friends are given a list of objects they need to find on the third floor and fourth level below ground, the first and fourth above ground, and ground level.
a. If ground level is 0 and the first level above ground is 1, which integers can you use to represent the other levels where objects are hidden? Explain please.
Above ground would be positive, and below ground would be negative. For example the third level below ground would be -3.
If ground level is 0 and the first level above ground is 1, which integers can you use to represent the other levels where objects are hidden? Explain your reasoning.
A building has 25 floors above the ground floor and 4 parking floors below it. The parking floors are numbered from P1 to P4, P4 being the lowest.
The lift travels from P2 to the 7th floor. How many floors did it ascend?
To represent the levels where the objects are hidden, we can use integers. Here's how we can assign integers to each level in the parking garage:
- Ground level: We can assign the integer 0 to represent the ground level since it is the starting point and corresponds to the value of zero in the number line.
- Below ground levels: To represent the levels below ground, we can use negative integers. In this case, we need to find objects on the fourth level below ground, so we can assign the integer -4 to represent this level. Similarly, the third level below ground can be represented by the integer -3.
- Above ground levels: To represent the levels above ground, we can use positive integers. We need to find objects on the first level above ground, so we can assign the integer 1 to represent this level. Likewise, the fourth level above ground can be represented by the integer 4.
Therefore, the levels where the objects are hidden can be represented by the following integers:
- Fourth floor below ground: -4
- Third floor below ground: -3
- Ground level: 0
- First floor above ground: 1
- Fourth floor above ground: 4
