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
Sherif's work on the autokinetic effect primarily demonstrates the power of <u>social roles</u>, and Asch's studies on line judgments demonstrate the power of <u>normative influence</u>.
Sherif's experiment showed group norms are set up through interaction of people and the leveling-off of excessive opinions. The end result is a consensus agreement that tends to be a compromise...even if it is wrong.
Muzafer Sherif performed a conventional look at on conformity in 1935. Sherif put subjects in a dark room and instructed them to look at a pinpoint of mild and say how a long way it moved. Psychologists had formerly discovered a small, unmoving light in a darkish room might appear to be transferring. This changed into categorized the autokinetic effect.
Sherif's work counseled that our information of the arena was encouraged by means of others within the absence of goal cues. Asch suggested that even with the physical cues, our perception of the arena is colored with the aid of others (or as a minimum our verbal behavior concerning the perception of the arena is colored by the group).
