an airplane travels 4688 kilometers against the wind in 8 hours and 5808 kilometers with the wind in the same amount of time. wh

Vladimir [108]

The speed of wind is 656 kmph and speed of plane is 70 kmph.

SOLUTION: 

Given that, an air-plane travels 4688 kilometers against the wind in 8 hours

And 5808 kilometers with the wind in the same amount of time.

We have to find the rate of the plane in still air and the rate of wind

Now, let the speed of wind be a kmph and speed of plane be b kmph.

And we know that, $\text { distance }=\text { speed } \times \text { time }$

$\begin{array}{l}{\text { Then, while travelling with wind } \rightarrow 5808=(a+b) \times 8 \rightarrow a+b=726 \rightarrow a=726-b \rightarrow(1)} \\\\ {\text { While travelling against wind } \rightarrow 4688=(a-b) \times 8 \rightarrow a-b=586 \rightarrow(2)}\end{array}$

Substituting (1) in (2) we get,

$\Rightarrow 726-b-b = 586\Rightarrow -2b=586-726 \Rightarrow -2b=-140$

$\Rightarrow b=\frac{140}{2} \Rightarrowb=70\Rightarrow (3)$

On substituting (3) in (1) we get,

$a=726-70=656\Rightarrow a=656$

Hence, the speed of wind is 656 kmph and speed of plane is 70 kmph.

Play room is 9 pounds of apples she needs 1 1/4 pounds to make one apple pie if she set aside 1.5 pounds of apples to make apple

kumpel [21]

Hi there!

I'm unsure if '11/4 pounds' meant '1/4', however, if it did, the answer is 6 pies in total.

Here's how I worked it out:
9 - 1.5 = 7.5 ( 1 )
7.5 - 1.5 = 6 ( 2 )
6 - 1.5 = 4.5 ( 3 )
4.5 - 1.5 = 3 ( 4 )
3 - 1.5 = 1.5 ( 5 )
1.5 - 1.5 = 0 ( 6 )

Hope I helped! (:

dolphi86 [110]

Answer:

29 ft x 58 ft

Step-by-step explanation:

Let x be the length of each side perpendicular to the wall, and y be the length of the side parallel to the wall.

The amount of wire available is:

$116 = 2x+y\\y=116-2x$
