Two airplanes depart from an airport traveling in opposite directions.
\n" ); document.write( " The second plane is 200 miles per hour faster than the first.
\n" ); document.write( " At 2 hours they are 1100 miles apart. Find the speeds of the airplanes.
\n" ); document.write( ":
\n" ); document.write( "Let s = speed of the 1st plane
\n" ); document.write( "then
\n" ); document.write( "(s+200) = speed of the 2nd
\n" ); document.write( ":
\n" ); document.write( "Write a dist equation; dist = time * speed
\n" ); document.write( ":
\n" ); document.write( "1st plane dist + 2nd plane dist = 1100 miles
\n" ); document.write( "2s + 2(s+200) = 1100
\n" ); document.write( ":
\n" ); document.write( "2s + 2s + 400 = 1100
\n" ); document.write( "4s = 1100 - 400
\n" ); document.write( "4s = 700
\n" ); document.write( "s = \"700%2F4\"
\n" ); document.write( "s = 175 mph is the 1st plane
\n" ); document.write( "then, obviously:
\n" ); document.write( "375 mph is the 2nd plane
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution
\n" ); document.write( "2(175) + 2(375) =
\n" ); document.write( "350 + 750 = 1100 \n" ); document.write( "
\n" );
