Step-by-step explanation:
the slower plane traveled x miles in 4 hours.
the faster plane traveled x + 4×80 = x + 320 miles in 4 hours.
so,
x + x + 320 = 3800 miles
2x =3480 miles
x =1740 miles (in 4 hours) .
that means the slower plane's speed was 435 mph.
and the faster plane's speed was 435 + 80 = 515 mph.
Step-by-step explanation:
doing with the ratio method
25 x
10 240
x=25×240÷10
Using the midpoint concept, it is found that the value of a is of a = 2.
<h3>What are the coordinates of the points?</h3>
Researching this problem on a search engine, the coordinates are given as follows:
<h3>What is the midpoint concept?</h3>
The midpoint between two points is the halfway point between them, and is found using the mean of the coordinates.
Hence the following system of equations can be built:
(b + 1 + 2a)/2 = 3.
b + 1 + 2a = 6.
b = 5 - 2a.
(a + 2 + 3b + 3)/2 = 5
a + 3b + 5 = 10
a + 3b = 5.
Since b = 5 - 2a, we have that:
a + 15 - 6a = 5.
5a = 10
a = 10/5
a = 2.
The value of a is of a = 2.

Let me think this again and I will get back later!! 2.234 graph
Remark
As long as the representation shows the numbers come one after another, you can get x to be anything.
Givens
x Can be the second number
x - 1 Can be the first number
x + 1 Can be the third number
x + 2 Can be the fourth number
Equation
x + x + 2= 132
Solution
2x + 2 = 132
2x = 130
x = 65
So the 4 numbers are 64 65 66 67
Check
The second and fourth numbers added together = 65 + 67 = 132
