Answer:
True
Step-by-step explanation:
The slope is the ratio of rise to run for any two points on a line.
The rise is the change in vertical axis, y
Rise = y2 - y1
The run is the change in the horizontal axis, x
Run = x2 - x1
Slope is the ratio of both:
Rise / Run = (y2 - y1) / (x2 - x1)
It takes 15 minutes for Ms. Peter to drive from park to her home
Given :
from her home to the park at an average speed of 30 miles per hour and
returned home along the same route at an average speed of 40 miles per hour
it takes 20 minutes to travel
Convert 20 minutes in to hour (divide by 60)
20 minutes = 1/3 hour
We know that distance = speed x time
From home to park, distance =![speed \cdot time =30 \cdot \frac{1}{3} =10 miles](https://tex.z-dn.net/?f=speed%20%5Ccdot%20time%20%3D30%20%5Ccdot%20%5Cfrac%7B1%7D%7B3%7D%20%3D10%20miles)
So , distance between home and park is 10 miles
Now we calculate the time taken to return from park to home
![time taken =\frac{distance}{speed} =\frac{10}{40}=\frac{1}{4}\\](https://tex.z-dn.net/?f=time%20taken%20%3D%5Cfrac%7Bdistance%7D%7Bspeed%7D%20%3D%5Cfrac%7B10%7D%7B40%7D%3D%5Cfrac%7B1%7D%7B4%7D%5C%5C)
Time taken is 1/4 hours. Convert it into minutes by multiplying by 60
![\frac{1}{4} \cdot 60=15](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%20%5Ccdot%2060%3D15)
So it takes 15 minutes for Ms. Peter to drive from park to her home
