Both trips were the same distance
\n" ); document.write( "Call the distance to the service station $\"d\"$ km
\n" ); document.write( " $\"d+=+r%2At\"$ and
\n" ); document.write( " $\"d%2Fr+=+t\"$
\n" ); document.write( " $\"d%2F60+%2B+d%2F15+=+4\"$
\n" ); document.write( "multiply both sides by 60
\n" ); document.write( " $\"d+%2B+4d+=+4%2A60\"$
\n" ); document.write( " $\"5d+=+240\"$
\n" ); document.write( " $\"d+=+48\"$ km
\n" ); document.write( "The round trip = $\"2d\"$
\n" ); document.write( "The round trip was 96 km answer \n" ); document.write( "
