Sherif was an organizer of current social brain research who built up a few one of a kind and intense systems for understanding social procedures, especially social standards, and social class. Huge numbers of his unique commitments to social brain science have been ingested into the field so completely that his part in the advancement and revelation has vanished. Different reformulations of social brain science have underestimated his commitments and spoke to his thoughts as new.
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
