<h2>
Speed of plane = 1110 kmph</h2><h2>
Speed of wind = 150 kmph</h2>
Step-by-step explanation:
Let the speed of plane be p and speed of wind be w.
Flying against the wind, an airplane travels 5760 kilometers in 6 hours.
Here
Speed = (p-w) kmph
Time = 6 hours
Distance = 5760 kmph
Distance = Speed x Time
5760 = (p-w) x 6
p-w = 960 -----eqn 1
Flying with the wind, the same plane travels 6300 kilometers in 5 hours.
Here
Speed = (p+w) kmph
Time = 5 hours
Distance = 6300 kmph
Distance = Speed x Time
6300 = (p+w) x 5
p+w = 1260 -----eqn 2
eqn 1 + eqn 2
p-w + p +w = 960 + 1260
2p = 2220
p = 1110 kmph
Substituting in eqn 2
1110 + w = 1260
w = 150 kmph
Speed of plane = 1110 kmph
Speed of wind = 150 kmph
Answer:
Step-by-step explanation:
Standard equation of an ellipse,

(h, k) is the center of the ellipse
Value of a = Distance of the center from the vertex
b = Distance of the center from the covertex
From the picture attached,
a = Distance of the center (h, k) from the vertex (2, -2) = 3 units
b = Distance of the center (h, k) from the co-vertex (-1, 0) = 1 unit
Center of the ellipse (h, k) = (-1, -2)
Answer: x= 26/3
Step-by-step explanation: Solve the rational equation by combining expressions and isolating the variable x.
Let's solve your equation!
4 + 2x
/6x = 12/5x
2x + 4/6x= 12/5x + 2/15
Multiply all terms by x and cancel:
- 2x + 4/6= 12/5
- 1/3x + 2/3 = 2/15x = 2/15x + 12/5 - 2/15x (Subtract 2/15x from both sides)
- 1/5x + 2/3 = 12/5
- 1/5x + 2/3 -2/3 = 12/5- 2/3 (subtract 2/3 from both sides)
- 1/5x = 12/5
- Multiply both sides by 5
- Check all your answers,
- x= 26/3
your answer is C I'm definitely sure
