Samir Flynn · Answer 1

Let's denote:

x: the time both trains traveled.

Then, we have:

70x + 80x = 390

=> 150x = 390

=> x = 390/150 = 2.6 hour

Madilynn Pruitt · Answer 2

2.6 hours (or 2 hours 36 minutes).

Step-by-step explanation:

The combined speed is 70+80 = 150 mph.

Speed = distance / time, so time = distance / speed.

So the time when they will meet

= 390 / 150

= 2.6 hours.
