Recall your d = rt, distance = rate * time
so, keeping in mind that both trains are going at the same speed, say speed of "r" mph, after 212 hours A arrived at station A and after 4 hours, B arrived at station B.
now, the distance covered by train A is say "d", we know both stations are 585 miles apart, so, if train A covered "d" miles in those 212 hours, then train B covered the slack from 585 and d, that is "585 - d".
Answer:
The equation for the description is: 
Step-by-step explanation:
We need to write an equation for the description.
The length of a rectangle is twice its width. The perimeter of the rectangle is 123 feet.
Let Width of rectangle = x
Length of rectangle = 2x (twice its width means, multiplying 2 with width)
Perimeter of rectangle = 123 feet
The formula used is: 
Putting values and finding equation:

So, the equation for the description is: 
You can simplify the equation as:

Both equations can be used:
