Using proportions, it is found that Ermias is traveling at a rate of 11 mph and Jeremiah at a rate of 19 mph.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Jeremiah travels 8 mph faster than Ermias, hence their velocities are:
x, x + 8
They travel in opposite directions, hence in one hour they are 2x + 8 apart.
In eight hours, the distance is 8(2x + 8), which is of 240 miles, hence:
8(2x +8) = 240
2x + 8 = 30
2x = 22
x = 11.
Then:
- x = 11 + 8 = 19 -> Jeremiah.

To find area we multiple length by width
20 times 45 is 900
then multiply that by 2 because there are two floors that are that size
900 times 2 is 1800
the total area for both floors is 1800 square feet
Answer:the distance is 8

Step-by-step explanation:
Answer:
y > -14
Step-by-step explanation:
-5(y+2) < 60
-5y - 10 < 60 (Expand the term on the left)
-5y < 70 (Bring the numbers to the right)
y > -14 (Divide both sides by -5. Note that the inequality sign changes as we are dividing by a negative number)
Hence Answer is <u>y > -14</u>
