Question 74492: a northbound train left the station at noon. 2 hours later a southbound train left the same station. At 6 the 2 trains were 450 miles apart. Find the rate of the 2 trains if the northbound train was traveling 25 mph faster than the southbound train Answer by checkley75(3666) (Show Source):
You can put this solution on YOUR website! 450=6(x+25)+4x
450=6x+150+4x
10x=450-150
10x=300
x=300/10
x=30 mph for the southbound train & 30+25=55 mph for the northbound train
proof
450=6*55+4*30
450=330+120
450=450
