Zachery · Answer 1

Let s = northbound train

Then

2s = southbound train

:

Distance = time * speed

4s + 4 (2s) = 600

:

4s + 8s = 600

:

12s = 600

:

s = 600/12

:

s = 50 mph is the northbound train

Then

2 (50) = 100 mph is the southbound train

Check:

4 (50) + 4 (100) = 600

Reagan Bullock · Answer 2

X + 2x = 600/4

x = 50

so one train is traveling 50 miles per hour

and the other is 100 miles per hour
