Answer:
Let x be the first piece, y the 2nd, Z the 3rd
You know all of the pieces together make 24 thus,
24 = x + y + z
The second piece is 2 times longer than the 1st so,
y = 2x
The 3rd is 5 times longer
z = 5x
Replace them in the equation of the beginning
24 = x + 2x + 5x
24 = 8x
x = 3 (First piece)
y = 6 (Second Piece)
z = 15 (Third Piece)
The answer would be D:9.2
11.35-6:35= 5 hours
5 x 4 = 20 this is how many degrees it rose in 5 hours
-18+20 = 2 degrees
d is your answer
