Answer:
175/3 or 58.333...
Step-by-step explanation:
This is fairly complicated but I will try to make it as simple as possible. I also apologize in advance for how impossible it is to make fractions look like fractions. I also had to insert a bunch of unnecessary parentheses just because the fractions that I can make are relatively inaccurate.
The distance between 2 cities can be represented as d.
Time is d/r if r is rate, so B->NY=d/50
Similarly,NY->B is d/70
Obviously the average speed is 2d/(d/50+d/70), this is just an average time
Now just remove the d and get (d/d)*2/(1/50+1/70)
You can now multiply by the LCM/LCM, which is 350/350.
After calculating you will get 700/12 which is 58.333...(This is how to enter into your RSM browser) Hope this helps. Sorry it is so late.

Answer:
Step-by-step explanation:
Use any two points from the line.
<u>Let them be: </u>
(x1,y1) = (0,-2)
(x2,y2) = (-1,0)
Now,
![\displaystyle Slope = \frac{y_2-y_1}{x_2-x_1} \\\\Slope = \frac{0-(-2)}{-1-0} \\\\Slope = \frac{2}{-1} \\\\Slope = -2\\\\\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20Slope%20%3D%20%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%20%5C%5C%5C%5CSlope%20%3D%20%5Cfrac%7B0-%28-2%29%7D%7B-1-0%7D%20%5C%5C%5C%5CSlope%20%3D%20%5Cfrac%7B2%7D%7B-1%7D%20%5C%5C%5C%5CSlope%20%3D%20-2%5C%5C%5C%5C%5Crule%5B225%5D%7B225%7D%7B2%7D)
