This initially neutral stimulus is called a <u>conditioned</u> stimulus.
A neutral stimulus on its own should produce no reaction, but if used together with an unconditioned stimulus (that causes either atraction or rejection), and after a series of repetitions, it will trigger the same reaction as the one generated by the unconditioned stimulus with which is paired.
This learning mechanism which involves an unconditioned stimulus, and a neutral one which becomes conditioned, is known as classical conditioning.
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
