Q. Noa helped his family prepare a holiday meal in their apartment kitchen,

29.3\,\text{m}

above ground level. Then he took a portion down to his neighbor, who lives

22\,\text{m}

above ground level in the same building. Answer

2

questions about Noa. What was Noa's change in height from his apartment to the neighbor's apartment? What is the vertical distance between Noa's apartment and the neighbor's apartment?

Calculate Heights Difference: To find Noa's change in height from his apartment to the neighbor's apartment, we need to calculate the difference in height between the two apartments. $\newline$ Calculation: $29.3\,\text{m}$ (Noa's apartment) - $22\,\text{m}$ (neighbor's apartment) = $7.3\,\text{m}$
Determine Direction of Movement: The change in height is a downward movement, so we can say Noa moved $7.3$ meters down to reach the neighbor's apartment.
Calculate Vertical Distance: The vertical distance between two points is the absolute value of the difference in their heights, regardless of the direction of movement. $\newline$ Calculation: The absolute value of $7.3\,\text{m}$ is still $7.3\,\text{m}$ , so the vertical distance between the apartments is $7.3\,\text{meters}.$
