Answer:
B. 30 minutes per day, 7 days a week
Explanation:
Adults need AT LEAST 30 minutes of physical activity every day. A week is 7 days.
The correct answer is swimming.
This is because it is the only individual sport among these options. All of the rest require a team to participate in. For example basket ball needs a team of 5 people at least. But in case of swimming you can race alone against all the other people.
Swimming is the self-propulsion of a person through fresh or salt water, usually for recreation, sport, exercise, or survival. It is one of the greatest sport in order to remain physically fit.
Characteristics of an Algorithm
Not all procedures can be called an algorithm. An algorithm should have the following characteristics −
Unambiguous − Algorithm should be clear and unambiguous. Each of its steps (or phases), and their inputs/outputs should be clear and must lead to only one meaning.
Input − An algorithm should have 0 or more well-defined inputs.
Output − An algorithm should have 1 or more well-defined outputs, and should match the desired output.
Finiteness − Algorithms must terminate after a finite number of steps.
Feasibility − Should be feasible with the available resources.
Independent − An algorithm should have step-by-step directions, which should be independent of any programming code.
Hope this helps!
