A passenger trains speed is 60 mi/h, and a freight speed is 40 mi/h. The passenger train travels the same distance in 1.5 h less time than the freight. How long does each train take to make the trip?
\n" ); document.write( "-----
\n" ); document.write( "Passenger train DATA:
\n" ); document.write( "rate = 60 mph ; time = x-1.5 hrs ; distance = rt = 60(x-1.5) = 60x-90 miles
\n" ); document.write( "-------------------
\n" ); document.write( "Freight train DATA:
\n" ); document.write( "rate = 40 mph ; time = x hrs ; distance = rt = 40x miles
\n" ); document.write( "-------------------
\n" ); document.write( "Equation:
\n" ); document.write( "distance = distance
\n" ); document.write( "40x = 60x-90
\n" ); document.write( "-20x = -90
\n" ); document.write( "x = 4.5 hrs (freight train time)
\n" ); document.write( "---
\n" ); document.write( "x-1.5 = 3 hrs (passesnger train time)
