It takes 1 hour longer to fly to St.Paul at 200mi/h than it does to return at 250mi/h. How far away is St.Paul?
\n" ); document.write( ":
\n" ); document.write( "Let t = time to St Paul
\n" ); document.write( "then
\n" ); document.write( "(t-1) = return time
\n" ); document.write( ":
\n" ); document.write( "Write a distance equation Dist = speed * time
\n" ); document.write( "250(t-1) = 200t
\n" ); document.write( "250t - 250 = 200t
\n" ); document.write( "250t - 200t = 250
\n" ); document.write( "50t = 250
\n" ); document.write( "t = $\"250%2F50\"$
\n" ); document.write( "t = 5 hrs to St.Paul
\n" ); document.write( ":
\n" ); document.write( "Find the distance: 5 * 200 = 1000 mi to St Paul
\n" ); document.write( ";
\n" ); document.write( "Check solution using return time: 4 * 250 = 1000 mi \n" ); document.write( "
