Represent the velocity of the boat as VB

Required
How to calculate the velocity of boat relative to river current
From the question, we understand that both move in the same direction.
So, the relative velocity V is calculated as:



Notice that the both velocities are added together to get the relative velocities.
This is so because they both move in the same direction
<em>From the list of given options, only option D is correct.</em>
Answer:
b. Power is centralized around one leader-the dictator
Explanation:
The nondemocratic regimes are usually led by one very powerful figure, a dictator. The dictator usually has all the power in the country, and there is no authority in the country that can limit him/her in his/hers actions. This often leads to a very unjust system in which the dictator does whatever he/she wants, while no one else has any say in it. The freedom of speech is lacking, the people that oppose the dictator end up in prisons or are murdered, the media is totally controlled, and the society is usually isolated from the rest of the world.
