Answer:
Distance to appointment point = 5 miles
Step-by-step explanation:
Let s be the distance to the appointment point,
We have Maria drove to a business appointment at 50mph in the morning.
Time taken in the morning
![t_m=\frac{s}{50}=0.02s](https://tex.z-dn.net/?f=t_m%3D%5Cfrac%7Bs%7D%7B50%7D%3D0.02s)
Her average speed on the return trip in the afternoon was 40 mph.
Time taken in the afternoon
![t_a=\frac{s}{40}=0.025s](https://tex.z-dn.net/?f=t_a%3D%5Cfrac%7Bs%7D%7B40%7D%3D0.025s)
Given that the return trip took 1/4hr longer because of traffic.
That is
![t_a-t_m=\frac{1}{4}hr=0.025hr](https://tex.z-dn.net/?f=t_a-t_m%3D%5Cfrac%7B1%7D%7B4%7Dhr%3D0.025hr)
Substituting
![t_a-t_m=0.025hr\\\\0.025s-0.02s=0.025\\\\s=5miles](https://tex.z-dn.net/?f=t_a-t_m%3D0.025hr%5C%5C%5C%5C0.025s-0.02s%3D0.025%5C%5C%5C%5Cs%3D5miles)
Distance to appointment point = 5 miles
500 • .03
the answer of that times two. then there is the answer
D^2 + 17d + 72 = 0
( d + 8 ) ( d + 9 ) = 0
d = - 8 , d = - 9
C. the outlier will most likely be the answer to this question
Square root of 3 is not rational, it is an irrational number
