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: D
Explanation:
OLDER WORKERS ARE NOT WILLING TO LEARN NEW SKILLS.
They also lack sufficient technological skills and are unable to learn new skills.
The traits of a hero are usually determined by all of these except for C - the plot of the story.
For that reason, the correct answer is probably a - cultural values, b - their experiences, d - their mentors.
It also makes sense that the different traits every hero has are rather complex when compiled together and the reasons why they have become as they have become have multiple reasons.
