You could solve this a few different ways the most simple of wich would be to set up an equation with a variable (x) representing time, in hours, connected to the speeds and where the sum of the two speeds equals 396 so:
95x + 85x = 396
Add together, solve for x
180x=396
x = 2.2 hours, or in minutes it would be 2 hrs 12 minutes.
95x + 85x = 396
Add together, solve for x
180x=396
x = 2.2 hours, or in minutes it would be 2 hrs 12 minutes.
Please let me know if I can be of further assistance, would love to meet in person to help you with further algebra problems.
Hello, thank you for taking the time to post your question!
The distance between the two trains grows by
95 mph + 85 mph = 180 mph
Meaning that for them to be 396 miles apart it will be
396 / 180 = 2.2 hours
I hope that helps you get moving in a better direction on this type of question! Feel free to reach out if you have any additional questions beyond that :)

95*t + 85*t= 396
180*t=396
t= 396/180
=2.2 hrs

This question cannot be answered given the information provided. It cannot be answered without knowing the paths that the rails lie along, the curves they take. Even with that information, the question would be difficult to answer.09/09/25
