Question 1187700: In Canada, eastbound and westbound trains travel
along the same track, with sidings to pull onto to
avoid accidents. Two trains are now 150 miles apart,
with the westbound train traveling twice as fast as
the eastbound train. A warning must be issued to pu
one train onto a siding, or else the trains will crash in
1-1/4 hours. Find the speed of the eastbound train and
the speed of the westbound train.

Two trains are now 150 miles apart,

So Distance = 150

the westbound train traveling twice as fast as
the eastbound train.

So let the eastbound train's rate is r.
Then the westbound train's rate is 2r.
Their approach rate is the sum of their rates, 3rSo

the trains will crash in 1-1/4 hours.

So 
DISTANCE = (RATE)(TIME)
    
    
    
    
    

The eastbound train's speed = r = 33 1/3 mph
The westbound train's speed = 3r = 100 mph
