Answer:
Both trains are traveling at 90 miles per hour.
Step-by-step explanation:
We are told that the rate is the same for both trains, and we know that the distance traveled by train a plus the distance traveled by train b equals 585 miles.
We will use
formula to solve this problem.
Train A:
(Using 2.5 instead of 2 and 1/2)
Train B: 
We can set an equation to solve for rate R of trains as:





Therefore, rate of both train a and train b is 90 miles per hour.
Answer:

Step-by-step explanation:
we know that
If the lines m and n are parallel
then
----> by corresponding angles
solve for x
