You can put this solution on YOUR website! Two trains leave the same station at the same time, one traveling East the other traveling West. At the end of 10 and 1/4 hour they are 1394 miles apart. If the rate of the train traveling East is 4 miles per hour faster than the rate of the other train find their rates.
***
let x=rate of train traveling West
x+4=rate of train traveling East
x+(x+4)=2x+4=rate at which the 2 trains are traveling apart
distance/traveling time=rate
1394/10.25=136
2x+4=136
2x=132
x=66
x+4=70
rate of train traveling West=66 mph
rate of train traveling East=70 mph
