the same time T required to drive a certain distance varies inversely with the speed R.
\n" ); document.write( " If it takes 2 hours to drive the distance at 40 miles per hour how long will it take to drive the same distance at 45 miles per hour?
\n" ); document.write( ":
\n" ); document.write( "An inverse relationship ratio equation, find the time (t) to drive the same dist at 45 mph
\n" ); document.write( "\"t%2F2\" \"40%2F45\"
\n" ); document.write( "cross multiply
\n" ); document.write( "45t = 2* 40
\n" ); document.write( "45t = 80
\n" ); document.write( "t = 80/45
\n" ); document.write( "t = 1.778 hrs which is: 1 + .778(60) = 1 hr 47 min
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Confirm this by finding the dist at each speed, should be the same
\n" ); document.write( "2 * 40 = 80 mi
\n" ); document.write( "1.778 * 45 = 80 mi \n" ); document.write( "
\n" );
