X + x + 1 + x + 2 = 12
x + x + x + 3 = 12
subtract 3 for each side
x + x + x = 9
3x = 9
divide 3 from each side
x = 3
Small side 3 feet
Middle side 4 feet
Long side 5 feet

Answer: 20
Step-by-step explanation:
So what I did was divide the pages by the hours and got 20

105 m = 2.5 h
x miles = 1 hour
You cross multiply since it's a proportion:
2.5 * x
105 * 1
=
2.5x = 105
Then you divide everything by 2.5
The answer is 42
