The time (t) of travel of an automobile trip varies inversely as the speed (v).
\n" ); document.write( " At an average speed of 65mph, a trip took 4h. The return trip took 5h.
\n" ); document.write( " Find the average speed of the return trip.
\n" ); document.write( ":
\n" ); document.write( "Let s = the speed on the return trip
\n" ); document.write( ";
\n" ); document.write( "the distance there and back is the same
\n" ); document.write( ":
\n" ); document.write( "Write a distance equation; dist = speed * time
\n" ); document.write( ":
\n" ); document.write( "5s = 4(65)
\n" ); document.write( "5s = 260
\n" ); document.write( "s = 260/5
\n" ); document.write( "s = 52 mph on the return trip
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "check solution by finding the distances, should be the same
\n" ); document.write( "65 * 4 = 260
\n" ); document.write( "52 * 5 = 260
\n" ); document.write( " \n" ); document.write( "
\n" );
