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:
many unknown variables that directly affect the individual's heart health condition.
Explanation:
The problem with this conclusion is that there are many unknown variables that directly affect the individual's heart health condition. Their socioeconomic status is one such variable since this determines whether or not the individual is able to afford the right types of food, healthcare, medicine, etc. All of these are vital components of maintaining a healthy heart and preventing heart disease.
