document.write( "Question 1018185: Two cars are traveling on two different routes, one 43 miles longer than the other. The car traveling on the longer route travels 2 miles per hour slower than the other car and it takes it 6 hours for the trip. If the car with the shorter route takes 5 hours for its trip, find the length of each route. \n" ); document.write( "

Let \"+s+\" = the speed of the car taking
\n" ); document.write( "the shorter route in mi/hr
\n" ); document.write( "\"+s+-+2+\" = the speed of the cat taking the
\n" ); document.write( "longer route in mi/hr
\n" ); document.write( "Let \"+d+\" = the distance of the shorter route in miles
\n" ); document.write( "\"+d+%2B+43+\" = the distance of the longer route in miles
\n" ); document.write( "---------------------------------------------
\n" ); document.write( "Equation for car taking the shorter route:
\n" ); document.write( "(1) \"+d+=+s%2A5+\"
\n" ); document.write( "euation for the car taking the longer route:
\n" ); document.write( "(2) \"+d+%2B+43+=+%28+s-2+%29%2A6+\"
\n" ); document.write( "----------------------
\n" ); document.write( "Substitute (1) into (2)
