122. The elevations (relative to sea level) of four locations are:
| Location | Elevation (m) |
|---|---|
| A | −180 |
| B | 1600 |
| C | −55 |
| D | 3200 |
(a) Which location is closest to sea level?
(b) Which location is farthest from sea level?
(c) Arrange the locations from the least to the greatest elevation.
(a) C
(b) D
(c) A, C, B, D
Least absolute value is closest to 0 (sea level): |−55|=55 (C). Largest absolute value is farthest: |3200| (D). For ordering, compare actual signed heights.
