1/15.999=x/54.5<br> Does anyone know what to do? I keep getting the answer wrong.

kkurt [141]

Hello!

First, let's write the problem.
$\frac{1}{15.999}=\frac{x}{54.5}$
Let's switch sides now, otherwise, we are going to end up doing it later.
$\frac{x}{54.5}=\frac{1}{15.999}$
Multiply both sides by 54.5.
$\frac{x}{54.5} *54.5 =\frac{1}{15.999}*54.5$
We could also rewrite that as,
$\frac{54.5x}{54.5}=\frac{1\cdot \:54.5}{15.999}$
Simplify.
$\frac{54.5x}{54.5}=x$
$\frac{1\cdot \:54.5}{15.999}=\frac{54.5}{15.999}$
$x=3.40646\dots$
That would be our final answer, we could round it to.
x ≈ 3.40

You can feel free to let me know if you have any questions regarding this!
Thanks!

at maximum speed, an airplane travels 2100 miles against the wind in 6 hours. flying with the wind, the plane can travel the sam

jok3333 [9.3K]

Plane's air speed is 437.5 mph
Wind velocity is 87.5 mph
An actual question hasn't been asked, but an educated guess would be to determine the plane's airspeed or the wind velocity. So I'll calculate those values for you.
When traveling with the wind, the combined speed is 2100/4 = 525 mph.
When traveling against the wind, the combined speed is 2100/6 = 350 mph.
So we can create 2 equations with 2 unknowns. They are:
a - b = 350
a + b = 525
Let's add the two equations together.
a - b = 350
a + b = 525
2a = 875
a = 437.5
So the plane's speed in still air is 437.5 mph.
Let's calculate the wind velocity.
a + b = 525
437.5 + b = 525
b = 87.5
And the wind velocity is 87.5 mph
