lori starts jogging at 5mph .
\n" ); document.write( " half an hour later debbie starts jogging at 7mph ,
\n" ); document.write( " how long will it take debbie to catch lori
\n" ); document.write( ":
\n" ); document.write( "Let t = jogging time for D to catch L
\n" ); document.write( "then
\n" ); document.write( "(t+.5) = jogging of L when she is caught
\n" ); document.write( ":
\n" ); document.write( "When this happens they both will have traveled the same distance
\n" ); document.write( "Write a dist equation; dist= speed * time
\n" ); document.write( "7t = 5(t+.5)
\n" ); document.write( "7t = 5t + 2.5
\n" ); document.write( "7t - 5t = 2.5
\n" ); document.write( "2t = 2.5
\n" ); document.write( "t = 2.5/2
\n" ); document.write( "t = 1.25 hrs for D to catch L
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this by finding the dist each traveled, should be the same
\n" ); document.write( "7 * 1.25 = 8.75 mi
\n" ); document.write( "5 * 1.75 = 8.75 \n" ); document.write( "
\n" );
