Charlie is riding in a bike race that goes through a valley and a nearby and by

Answer 1

(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:

`-198+369=171\text{ ft}`

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:

`\begin{gathered} -65-(-198)=-65+198 \\ =133\text{ feet} \end{gathered}`

Checkpoint 2 is 133 feet lower than Checkpoint 5.
