Question 801234
Two trains leave the train station traveling the same rate of speed.
 The southbound train reaches its destination in 1.5 hours.
 The northbound train reaches its destination in 2 hours.
 How fast were the trains traveling if their destinations are 200 miles apart?
:
Let s = the speed of the trains
:
Write a distance equation, dist = time * speed
:
First train dist + 2nd train dist = 200 mi
1.5s + 2s = 200
3.5s = 200
s = 200/3.5
s = 57.14 mph is their speed
:
:
See if that checks out, find the dist each traveled
1.5(57.14) = 85.7 mi
2.0(57.14) = 114.3 mi
---------------------
total dist: 200 mi
