First, we want to convert 600 feet to inches:
600 feet (12 inches/ft) = 7200 inches
We know that the diameter is 60 inches, so the circumference is 60π inches or 188.5 inches.
We can divide 7200/188.5 to get about 38.2 rotations.
Given:
40 pages in 1.6 minutes
40 / 1.6 = 25 pages per minute
25 x 5 minutes = 125 pages
40 / 1.6 = x / 5
40*5 = 1.6x
200 = 1.6x
200/1.6 = x
125 = x pages
25 : 1 = 150 : x
25x = 150
x = 150/25
x = 6 minutes
The answer is A. -∞ < y < 2
Thirty-eight is 38
Ninety seven hundredths is 0.97
So the whole thing would be 38.97
