The current world records for the highest parachute jump and the lowest mannedvessel ocean dive were both set in $1960 .$ On August 16 of that year, Captain Joseph Kittinger jumped from a height of $102,880$ ft above sea level. Earlier, on January $23,$ Jacques Piccard and Navy Lieutenant Donald Walsh descended in a bathyscaphe $35,797$ ft below sea level. What was the difference in elevation between the highest parachute jump and the lowest ocean dive?

Key Concepts

Measurement Units

Using consistent measurement units, such as feet or meters, is essential for accuracy in calculations. This practice allows different vertical measurements to be directly compared and combined without conversion errors.

Elevation

Elevation refers to the vertical distance of a point relative to a reference level, typically sea level. This concept includes both points above sea level (referred to as altitude) and below sea level (referred to as depth), and is fundamental when comparing vertical positions.

Absolute Difference

The absolute difference is the total distance between two values regardless of their direction. In the context of vertical measurements, it involves summing the magnitudes of the distances above and below the reference point to find the overall separation.

Arithmetic Subtraction

Arithmetic subtraction is a basic mathematical operation used to determine the difference between two numerical values. When dealing with elevations that are measured in different directions (above and below sea level), correct subtraction or the use of absolute values ensures accurate calculation of total vertical distance.
