Answer:
45 km/hr
Explanation:
total distance = 90
Increased speed = x+15
90/x - 90/x+15=1/2
90(1/x - 1/x+15)=1/2
90(x+15-x/x^2+15x)=1/2
equation is:
x^2+15x-2700=0
x^2+60x-45x-2700=0
x(x+60)-45(x+60)=0
(x+60)(x-45)=0
x= -60, x=45
reject the negative value = -60
usual speed=45 km/ hr
The answer is subconscious. It is because our subconscious is the part of the mind in every individual in which a person is not fully aware of all the things around him or her but in a way these influences other people without knowing it and the defense mechanism are the one responsible for protecting an individual in things that may affect the person without knowing it such as his or her feelings.
