The table given below shows the elevations relative to sea level of four locations. Taking sea level as zero, answer the following questions:
Location Elevation (in 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.

Solution:

To answer the given questions let us examine the problem deeply using the properties of integers.

1. As per the given tabular data, C is closest to sea level.
2. As per the given tabular data, D is farthest from sea level.
3. As per the given tabular data we have, -180 < -55 < 1600 < 3200. According to this the locations from the least to the greatest elevation can be arranged as A < C < B < D.

✦ Try This: From the given data calculate the elevation distance between location D and B.

Now to find the elevation distance between location D and B we can apply integer rules and the rules of subtraction.
