Answer 1

Given:

The altitude for checkpoint 2 is -47.

The altitude for checkpoint 3 is -216.

The altitude for checkpoint 4 is 2,001.

Required:

a) we need to find the altitude of checkpoint 4 higher than checkpoint 2.

b) we need to find the altitude of the top of the hill when that rises 329 feet about the checkpoint 3.

Step-by-step explanation:

a)

The difference between 2001 and -47 is

`2001-(-47)=2001+47=2048.`

Checkpoint 4 is 2048 ft higher than checkpoint 2.

b)

Add 329 to the altitude of the checkpoint 3.

`-216+329=113`

The altitude of the top of the hill is 113 ft.

Final answer:

a) Checkpoint 4 is 2048 ft higher than checkpoint 2.

b) The altitude of the top of the hill is 113 ft.
