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

The correct answer is letter C.
Explanation: Photosynthesis is performed by activated cells that use chlorophyll, a pigment capable of transforming light energy into chemical energy that can be harnessed directly by living beings, as opposed to light. In this reaction, the atomic groups of carbon dioxide, water and mineral salts, in the presence of light, are transformed into gas and sugar.
The producer within each of his cells (specifically the mitochondria of all cells) uses and transforms glucose (a type of sugar), releasing energy that the cell can use in its activities. This process is known as cellular respiration.
