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.
If you plot the points you can easily find the answer. (X,Y) The x-axis is the horizontal line and the y-axis is the vertical line.
The answer is -1/16 or -0.0625, do you need to see work?
Answer:
Step-by-step explanation:
Y=8(32)+12
Y=256+12
Y=268 (Sandra)
Y=8(24)+12
Y=192+12
Y=204 (Bela)
204+268=472
