Answer:
In order to keep track of all conditional formatting used in a worksheet, we use the manage rules menu command under conditional formatting.
Explanation:
Conditional formatting can help make patterns and trends in your data more apparent.
What is the use of conditional formatting?
Conditional formatting makes it easy to highlight certain values or make particular cells easy to identify. This changes the appearance of a cell range based on a condition (or criteria). You can use conditional formatting to highlight cells that contain values that meet a certain condition. To use it, you create rules that determine the format of cells based on their values, such as the following monthly temperature data with cell colors tied to cell values. They are grouped into three categories: Data Bars are horizontal bars added to each cell, much like a bar graph. Color Scales change the color of each cell based on its value. Each color scale uses a two- or three-color gradient. Conditional formatting hence enables you to apply special formatting to cells in your spreadsheet that meet certain criteria.

The advantage of encapsulation is it enables changes to implementation without changing a class's contract and causes no consequential changes to other code.
The definition of encapsulation is the grouping of data into a single unit. It is the mechanism that connects the data the code manipulates with the code itself. Encapsulation can also be viewed as a barrier that stops code from the outside of the barrier from accessing the data.
Technically speaking, encapsulation means that a class's variables or data are concealed from all other classes and are only accessible through member functions of the class in which they are stated.
It is also known as a combination of data-hiding and abstraction because, similar to encapsulation, the data in a class is hidden from other classes using the data hiding concept, which is accomplished by making the members or methods of a class private, and the class is exposed to the end-user or the world without providing any details behind implementation.
Encapsulation can be accomplished by writing public methods in the class to set and get the values of variables and declaring all of the class's variables as private. With the setter and getter methods, it is more clearly described.

Answer:
At a time the maximum number of bits is 1600000000
Explanation:
First, we must work with the same units, changing the distance into meters we have: 1km = 1000m
48*10^3km *1000m equals 48* 10^6m
Formula for Time=Distance/Speed
48*10^⁶m / 240000000 equals 0.2 seconds.
