It will take 120 minutes to chop down 100 trees.
Bob chops 10 trees in 30 minutes, so he can chop 100 trees in 300 minutes.
Frank chops 15 trees in 30 minutes, so he can chop 100 trees in 200 minutes.
Solve this using the following equation:
15 / 30 = 100 / x
Solving for x gives 120 minutes.

Answer:
<em>b = 15</em>
Step-by-step explanation:
4(b + 5) = 3b + 35
Distribute:
4(b + 5)
4(b) = 4b
4(5) = 20
4b + 20 = 3b + 35
Combine like terms:
4b - 3b = 35 - 20
b = 15
<span>Let the width of the rectangular plot of land be 'x' yards.
Given that the length of the rectangular plot of land is 10 yards more than its width.
So, width of the rectangular plot of land = (x + 10) yards.
Also given that the area of the rectangular plot of land is 600 square yards.
We know that, area of a rectangle = length * width
That is, (x+10) * x = 600
x^2 + 10x = 600
x^2 + 10x - 600 = 0
x^2 + 30x - 20x -600 = 0
x(x + 30) - 20(x + 30) = 0
(x +30)(x -20) =0
Therefore, either (x + 30) = 0 or (x - 20) = 0
If x + 30 = 0, then x = -30 and
If x - 20 = 0, then x = 20
Since 'x' represents the width of a rectangular plot of land it cannot be negative.
Therefore,
width of the rectangular plot of land = 20 yards
length of the rectangular plot of land= x + 10 = 30 yards</span>
