You can put this solution on YOUR website!
Distance(d) equals rate(r) times Time(t) or d=rt; r=d/t and t=d/r\r
\n" ); document.write( "\n" ); document.write( "Let t=number of hours that has elapsed when they are 69 miles apart\r
\n" ); document.write( "\n" ); document.write( "In t hours car-1 travels 32*t miles
\n" ); document.write( "In t hours car-2 travels 47*t miles\r
\n" ); document.write( "\n" ); document.write( "Now we are told that:
\n" ); document.write( " 47t-32t=69 collect like terms\r
\n" ); document.write( "\n" ); document.write( "15t=69 divide both sides by 15
\n" ); document.write( "t=4.6 hr------------------------------ans\r
\n" ); document.write( "\n" ); document.write( "CK
\n" ); document.write( "47*4.6-32*4.6=69
\n" ); document.write( "216.2-147.2=69
\n" ); document.write( "69=69\r
