jok3333 [9.3K]

Answer:

90 \leqslant x \leqslant 150

Step-by-step explanation:

You need at least $90 dollars, so x will be bigger than or equal to that amount.

Your parents don't want to give you more than $150 dollars so x is smaller than or equal to that amount.

An airplane travels 600 miles against the wind in 4 hours, and makes the return trip with then same wind in 2 hours. Find the sp
SOVA2 [1]

Answer:

The speed of wind is 75 miles / hour

Step-by-step explanation:

Let's assume

speed of airplane is x miles /hour

speed of wind is y miles /hour

Against wind:

An airplane travels 600 miles against the wind in 4 hours

against wind means resultant speed will be less

so, speed =x-y

total distance traveled in 4 hour is

=4(x-y)

and this has to be equal to 600

600=4(x-y)

Divide both sides by 4

and we get

x-y=150

With wind:

makes the return trip with then same wind in 2 hours

with wind means resultant speed will be more

so, speed =x+y

total distance traveled in 2 hour is

=2(x+y)

and this has to be equal to 600

600=2(x+y)

Divide both sides by 2

and we get

x+y=300

So, we get system of equations

x-y=150

x+y=300

now, we can solve it by adding both equations

x-y+x+y=150+300

2x=450

now, we can solve for x

x=225

now, we can  find y by plugging x into any one equation

225+y=300

y=75

So,

The speed of wind is 75 miles / hour
