Algebra.Com's Answer #511529 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! a freight train leaves the train station 1 hour before a passenger train. \n" ); document.write( " The two trains are traveling in the same direction on parallel tracks. \n" ); document.write( " if the rate of the passenger train is 5 mph more than the freight train, \n" ); document.write( " how fast is each train traveling if the passenger train passes the freight train in 12 hours? \n" ); document.write( ": \n" ); document.write( "When the pass train catches the freight, they will have traveled the same dist. \n" ); document.write( "From the information given we know the travel time of the pass is 12 hrs and the travel time of the freight is 13 hrs \n" ); document.write( ": \n" ); document.write( "let s = the speed of the freight \n" ); document.write( "then \n" ); document.write( "(s+5) = speed of the pass train \n" ); document.write( ": \n" ); document.write( "Write a distance equation: dist = speed * time \n" ); document.write( "13s = 12(s+5) \n" ); document.write( "13s = 12s + 60 \n" ); document.write( "13s - 12 = 60 \n" ); document.write( "s = 60 mph is the speed of the freight \n" ); document.write( "You can find the speed of the pass \n" ); document.write( "; \n" ); document.write( ": \n" ); document.write( "Pretty easy, right? \n" ); document.write( ": \n" ); document.write( ": \n" ); document.write( "YOu can confirm this by finding the actual dist each train went, should be the same. \n" ); document.write( " |
