A.
For 12 - 1,
82 - 78 = 4 degrees per hour
For 1 - 3:15,
(88 - 82) / 2.25 = 2.67 degrees per hour
For 3:15 - 4:30,
(93 - 88) / 1.25 = 4 degrees per hour
For 4:30 to 6,
(91 - 93) / 1.5 = 1.33 degrees per hour
The time intervals 12 to 1 and 3:15 to 4 had the fastest rate of change
Answer:
Step-by-step explanation:
x+y = 60
x-y = 8
------------
2x = 68
x = 34
y = 60-x = 26
X/3-10=12
x/3=-2
x=-6
p/5+10=14
p/5=4
p=20
