Flying against the wind, a jet travels 2160 miles in 3 hours. Flying with the wind, same jet travels 6000 miles in 6 hours. What
marissa [1.9K]

Answer:

The velocity of jet in still air is  860miles/hour and velocity of wind is   140miles/hour.

Step-by-step explanation:

Let x be the rate of the jet in still air and y be the rate of the wind.

Given:

Velocity against wind, a jet travels 2160 miles in 3 hours.

Velocity against wind =\frac{2160}{3} = 720 miles/hour

Flying with the wind, same jet travels 6000 miles in 6 hours.

Flying with the wind =\frac{6000}{6} = 1000 miles/hour

As such its velocity against wind is  x-y

and with wind is   x+y therefore

x-y=720------------(1)

x+y=1000---------------(2)

Adding equation 1 and 2.

2x=1720

x=\frac{1720}{2}

x=860

Put x value in equation 2

860+y=1000

y=1000-860

y=140

Hence velocity of jet in still air is  860miles/hour and velocity of wind is   140miles/hour.

(2x - 5) (5x - 10)
Use FOIL
10x² - 20x - 25x + 50

10x²  - 45x + 50
 

5( 2x² - 9x + 10)

     2x           -5 
      x             -2

5(2x - 5)(x -2)

make each equal to 0
2x - 5 = 0
x - 2 = 0

2x - 5 = 0                        x - 2 = 0
2x - 5 (+5) = 0                x - 2 (+2) = 0 (+2)
2x = 5                             x  = 2
x = 5/2

x = 5/2 , 2

hope this helps
