The speed of the airplane is 360 km/h while the speed of the wind is 40 km/h.
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Let a represent the speed of the airplane and b represent the speed of the wind, hence:
(a + b)6 = 2400
a + b = 400 (1)
Also:
(a - b)7.5 = 2400
a - b = 320 (2)
From eqn 1 and 2:
a = 360 km/h, b = 40 km/h
The speed of the airplane is 360 km/h while the speed of the wind is 40 km/h.

The system of inequalities that represents this situation are
x + y ≤ 40 and x ≤ 12.
Here, x = Number of carnation bouquets
y = Number of daisy bouquets
From the system of inequalities,
In the first case.
The local florist has never more than a combined total of 40 daisy bouquets, so according to this statement the following equation will be:
x + y ≤ 40.
Again in the second case.
The local florist has never more than a 12 carnation bouquets, so according to this statement the following equation will be:
x ≤ 12.
Therefore, the system of inequalities that represents this situation are
x + y ≤ 40 and x ≤ 12.

Step-by-step explanation:
Answer:
Erie to Rochester is 145 miles
Step-by-step explanation:
If we designate the points of interest as C, E, and R, we are told that ...
CE + ER = CR . . . . . the various distances are segments of a straight line
For CE = 94 and CR = 239, we can fill in the given information and solve for ER.
94 + ER = 239
ER = 239 -94 . . . . . . subtract 94 from both sides of the equation
ER = 145
The distance from Erie to Rochester is 145 miles.
