A jet travels 4680 miles against the wind in eight hours and 5720 miles in the wind in the same amount of time what is the rate
Kryger [21]

9514 1404 393

Answer:

  • jet: 650 mph
  • wind: 65 mph

Step-by-step explanation:

The speed against the wind is ...

  4680 mi/(8 h) = 585 mi/h

The speed with the wind is ...

  5720 mi/(8 h) = 715 mi/h

The speed of the airplane in still air is the average of these speeds:

  (585 +715)/2 = 650 mi/h . . . speed in still air

The speed of the wind is the difference between the airplane speed and the speed in the wind:

  715 -650 = 65 mi/h . . . speed of the wind

_____

<em>Additional comment</em>

If p and 'a' represent the speeds of the plane and the air, the speeds with and against the wind are ...

  p + a = with

  p - a = against

If we average these, we get ...

  ((p +a) +(p -a))/2 = (with + against)/2

  p = (with + against)/2 . . . . . . . the formula we used above

Mother bought a basket for 10% discount.how much is the tag price if the price was Php250.00?​
Svetllana [295]

Answer:

The tag price would be 275 dollars.

Step-by-step explanation:

10% of 250.00 is 25. But the tag price is without the discount and the 250.00 is with the discount. So, if you add 25 to 250 you get 275.
