Speed is given by the distance traveled divided by the time spent.

The net speed with which the plane traveled against the wind is given by \frac{236}{1.4} =168.57\ mi/hr while the speed with which the plane travelled in the return trip is given by \frac{236}{1} =236\ mi/hr 

Let the speed of the plane be v and the speed of the wind be w, then when the plane was traveling against the sun, we have, v - w = 168.57 and when the plane is travelling in the direction of the wind, we have, v + w = 236.

 Subtracting the first equation from the second equation, we have: 2w = 236 - 168.57 = 67.43

Thus, w = 67.43 / 2 = 33.715

Therefore, the speed of the wind is approximately 33.7 mi/hr.

The first thing we must do for this case is to define variables:
 v1: speed of the plane
 v2: wind speed
 We then have the following system of equations:
 With the wind against:
 v1 - v2 = 236 / 1.4
 Wind in favor:
 v1 + v2 = 236/1
 Solving the system we have:
 v1 = 202.286
 v2 = 33.71
 Answer:
 the speed of the wind is:
 v2 = 33.7 miles / hour

What is the answer to 1n-10=5/6-7-1/3n
navik [9.2K]
1*n-10 = (5/6)*n-((1/3)*n)-7 // - (5/6)*n-((1/3)*n)-7

1*n-((5/6)*n)+(1/3)*n-10+7 = 0

n+(-5/6)*n+(1/3)*n-10+7 = 0

1/2*n-3 = 0 // + 3

1/2*n = 3 // : 1/2

n = 3/1/2

n = 6

That's just in case you had to show your work lol^^
