Question 803345
Distance traveled by both trains together = 120 miles

west bound train speed be x
east bound train speed = (x+8)

They are moving away so add up speeds . x+x+8=2x+8 mph

t=d/r

2=120/(2x+8)

2x+8 =120/2

2x+8 =60

2x=60-8
2x=52
x=27 mph

speed of east bound train = 27 mph
the other will be 27+8 = 35 mph
