Sarah wants to find out how much time it would take to drive from her home to New York. At an average, she would drive at 55 miles per hour. If the distance to be covered is 1150 km and a mile equals 1.61 km, how much time will the trip take (to the nearest hour)? O 13 hours 21 hours 29 hours 34 hours
Answer:
45 miles
Explanation:
Speed = distance / time
Lets assume :
speed = x
Distance = D
Time = 3 hours
so in first case :
x = D / 3
D = 3x
Second case :
speed = x-5 ( he is traveling 5mph slower )
Distance = D ( Distance is same )
time = 4.5 hour
so,
x-5 = D / 4.5
D = 4.5(x-5)
since D is same in both cases.
3x = 4.5(x-5)
3x = 4.5x - 22.5
4.5x - 3x = 22.5
1.5x = 22.5
x = 22.5/1.5
x= 15
so speed is 15mph
D= 3x
so Distance = 3*15 = 45 Miles.

Information is power and insight can impact on public discourse. This way, perceptions can be changed by access to media. Different types of media are utilised globally to distribute knowledge and idealistically, free mass media is a tool of and signpost for democracy. Freedom of expression is not only the core of a healthy media but also a fundamental human right and vital for a democratic structure. It stands for freedom of speech, the right to information and the representation of different opinions in a heterogeneous society. In any culture of prevention, effective and democratic media are an essential part and indispensable for societies trying to make a transition towards peace and democracy. Harry S. Truman once said “You can never get all the facts from just one newspaper, and unless you have all the facts, you cannot make proper judgements about what is going on”[1]– this statement reflects the need for free access to unbiased information. Not giving people the possibility of political participation and not allowing them to express themselves freely is a significant cause of conflict. On the one hand free, independent and pluralistic media provide a platform for debate and different opinions. On the other hand, media can be misused for propaganda purposes, to incite hatred and spread rumours and therefore artificially create tensions[2]. The transmission of ideas is also not limited to conventional media such as newspapers, TV or radio. Arguably, the traditional media takes primacy in this, however, new technologies, the internet and digital content should also be considered in this contex
Lack of information can, at any stage of a conflict, make people desperate, restless and easy to manipulate. The ability to make informed decisions strengthens societies and fosters economic growth, democratic structures and the positive outlook on the future. For this very reason, the United Nations Millennium Declaration stressed the need “to ensure the freedom of the media to perform their essential role and the right of the public to have access to information”[4].
Journalism does not need justification for its existence. Its service to society is justification in itself. Journalism can not only help to distribute information but also counter hate-speech and create an environment of balanced opinions, an information equilibrium[5]. For the media it can be problematic to find a balance between preventing harm caused by speech and protecting individual expression. Being able to find this balance, however is important especially in conflict situations. Responsible journalism does not just re-publish press releases but is truly concerned with a truthful, balanced and fair account of events. In order to achieve this journalists have to stay clear of judgemental representations and describe reality without embellishment[6]. If democracy is to work properly, society needs access to news and information; analysis of the status quo, debate, practical information and exchange as well as entertainment are needed and provided by the media. The definition of conflict and defining conflict areas is not easy and no two places are alike. Journalists need to know what they can expect on sight in order to define the objectives of their project.[7]
In case of a crisis or a conflict, the international media can attract worldwide attention. The mass media is a pervasive part of daily life especially in industrialised countries and thus able to shine a light on conflicts anywhere in the world. Since most armed conflicts these days have governmental and not territorial reasons; the parties are often concerned with making sure that the majority of people are on “their” side, which bears a lot of potential for misrepresenting facts and trying to seize control over the distribution of information. For this very reason the intervention of unbiased and free global media is important not only for the world public but also for the people directly affected. The number of conflicts, however, that gets international attention is small; therefore local media is vital in this context[8].
