The cities should be sorted from closest to farthest from sea level as follows; Sydney → Bombay Beach → Jericho.
In order to sort the distance of the cities from sea level, we would calculate the new distances relative to sea level by finding the absolute value of each distance.
Note: The sea level is typically at 0 meter.
By taking the absolute value of the distances, we have:
Jericho: |-258.3| = 258.3 meters
Sydney: |19.7| = 19.7 meters
Bombay Beach: |-69.1| = 69.1 meters
In this context, we would sort the distances from closest (lower) to farthest (higher) as follows:
Sydney: 19.7 meters.
Bombay Beach: 69.1 meters.
Jericho: 258.3 meters.
