i hope i am within a hundred miles of it that will give me time to get there i havent seen a good train wreck in a long time
i wouldent want to be where they were 3.4 hours from now
45 + 89 = 134 mph x 3.40 hours = 455.6 miles
if you want it closer than that add a .001 or .002 to that
now, convert the decimal to minutes by multiplying .40 by 60 to find that it is equal to 25 minutes.
your answer comes to 3 hrs and 25 min. QED

They will collide when they've traveled 456 miles. How many miles can they cover in an hour? Let's see. One of them covers 45 mph, and theother 89. So that's what, 134?
If you cover 134 miles per hour, how long would it take to cover 456 miles?

Wow I'm looking at that train crash in Chicago right now on CNN...
They don't know how long it took either.

About 2 hours 25 minutes...that is my best guess. D

My condolences to the victims. Can we start a fund for the children?
