Answer:
74 deg
Step-by-step explanation:
Ok, so this is a bunch of steps.
I assume you are referencing y=mx+b. The equation gives you the slope of the line (m), and a coordinate (x, y). As well as b, which could be used for many things.
We are trying to find the average speed of the plane, which is mph, or
. Using proportions, we can find the average speed of the plane in mph:

- Use the information from the problem to create a proportion. Remember that we are looking for mph, so we will call that
.

- Multiply the entire equation by


- Divide both sides of the equation by
to clear both sides of the mile unit
The average speed of the plane is 300 mph.
Answer:
Step-by-step explanation:
Cross multiplying
5z =14*24
5z = 336
Divide by 5
z = 336/5
Or mixed fraction z= 67(1/5)
Decimal z= 67.2
