It is 600
u could have just looked it up...
Let
be the speed of train A, and let's set the origin in the initial position of train A. The equations of motion are

where
are the positions of trains A and B respectively, and t is the time in hours.
The two trains meet if and only if
, and we know that this happens after two hours, i.e. at 

Solving this equation for v we have

So, train A is travelling at 105 km/h. This implies that train B travels at

Answer:
u can be using it at perpendicular and place it's center on point A
hope that helps a bit-
Answer:find the slope
Step-by-step explanation:
I don't know if you know how to find the slope if not reply back. But that's what the equation wants you to do.
Answer:
subtract 8x from both sides
Step-by-step explanation:
this is the first step
