At maximum speed, an airplane travels

Mathematics
1 answer:
SpyIntel [72]3 years ago
3 0

against wind the speed = x-y

distance traveled = 2460

2460/x-y= 6

6x-6y= 2460

x-y=410...........1

..

with wind speed = x+y

distance is same 2460

2460/x+y=5

5x+5y=2460

x+y=492............2

..

Add equation 1 & 2

x-y+x+y=410+492

2x=902

x= 451 mph speed of plane in still air.

..

Plug the value of x in equation 1

451-y=410

y=451-410

y=40 mph the speed of wind

.

Order the fractions from least to greatest
My name is Ann [436]

Answer:

1/4, 2/5, 1/2, 3/5, 2/3, 13/18, 7/9, 5/6, 2 6/15, 2 4/9, 2 3/5, 2 2/3, 6 3/8, 6 1/2,

6 3/4, 6 5/6

Step-by-step explanation:

I like to organize decimals more than fractions because it's easier for me, so I'm changing each of them to a decimal. You don't have to do this though.

  1. To change a fraction to a decimal, if it is simplified, make it an improper fraction
  2. Then, divide the numerator from the denominator. For example, 1/4 = 0.25 because 1 divided by 4 = 0.25
  • 3/5 = <u>0.60</u>,
  • 1/4 = <u>0.25,</u>
  • 1/2 = <u>0.50</u>,
  • 2/5 = <u>0.40</u>,
  • 7/9 = 0.7 repeating or just <u>0.78 </u>rounded,
  • 13/18 = 0.72 repeating or <u>0.73</u> rounded,
  • 5/6 = 0.83 repeating or <u>0.84 </u>rounded,
  • 2/3 = 0.66 repeating or <u>0.67</u> simplified,
  • 6 3/4 = 27/4 or <u>6.75</u>,
  • 6 1/2 = 13/2 = <u>6.50,</u>
  • 6 5/6 = 41/6 = 6.83 repeating or <u>6.84</u>
  • 6 3/8 = 51/8 = 6.375 or <u>6.38</u>
  • 2 2/3 = 8/3 = 2.66 repeating or <u>2.67</u>
  • 2 6/15 = 36/15 = <u>2.40</u>
  • 2 3/5 = 13/5 = <u>2.60</u>
  • 2 4/9 = 22/9 = 2.44 repeating or <u>2.45</u>

<u />

Ordering them is pretty easy, just start from the smallest and move to the greatest!

  1. 0.25 = 1/4
  2. 0.40 = 2/5
  3. 0.50 = 1/2
  4. 0.60 = 3/5
  5. 0.67 = 2/3
  6. 0.73 = 13/18
  7. 0.78 = 7/9
  8. 0.84 = 5/6
  9. 2.40 = 2 6/15
  10. 2.45 = 2 4/9
  11. 2.60 = 2 3/5
  12. 2.67 = 2 2/3
  13. 6.38 = 6 3/8
  14. 6.50 = 6 1/2
  15. 6.75 = 6 3/4
  16. 6.84 = 6 5/6
