Answer:
(a)171 ft
(b)133 feet lower
Explanation:
Part A
The altitude of Checkpoint 2 = -198 feet
The top of a hill rises 369 feet above checkpoint 2.
Therefore, the altitude of the top of the hill is:
[tex]-198+369=171\text{ ft}[/tex]
The altitude of the top of the hill is 171 feet.
Part B
• The altitude of checkpoint 2 = -198 ft
,
• The altitude of checkpoint 5 = -65
The difference in the altitudes is calculated below:
[tex]\begin{gathered} -65-(-198)=-65+198 \\ =133\text{ feet} \end{gathered}[/tex]
Checkpoint 2 is 133 feet lower than Checkpoint 5.
