Im pretty sure the answer is t = 50 + 91.40n
Answer:
Step-by-step explanation:
Let the speed of plane is p and speed of the wind is w.
<u>Then we have:</u>
- 10*(p + w) = 1120 ⇒ p + w = 112
- 20*(p - w) = 1120 ⇒ p - w = 56
<u>Sum the two equations and solve for p:</u>
- p + w + p - w = 112 + 56
- 2p = 168
- p = 84
<u>Find w:</u>
- 84 + w = 112
- w = 112 - 84
- w = 28
Answer:
520miles per day
Step-by-step explanation:
2080/4=520
Y^2 = (2x+1)/(x-1)
xy^2-y^2 = 2x + 1
xy^2 - 2x = y^2 + 1
x(y^2 - 2) = y^2 + 1
x = (y^2 + 1) / (y^2 - 2)
