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
Answer:
Elaborative rehearsal
Explanation:
Elaborative rehearsal: In psychology, the term elaborative rehearsal is defined as a phenomenon that is responsible for encoding particular information into an individual's long-term memory with the help of brain-processing that information in depth.
It helps an individual to make an association or connection between a piece of information that he or she is trying to learn and the formerly present information in his or her memory.
It encompasses deep semantic processing of a piece of information yet to be remembered that leads to the development of durable memories and it is considered as more effective as compared to maintenance rehearsal.
In the question above, the given statement signifies the importance of elaborative rehearsal.
