A car traveled 50 mph between two towns.
\n" ); document.write( " If the speed had been 10 mph faster, the trip could have been made in 1 hr. less time.
\n" ); document.write( "How far apart are the towns?
\n" ); document.write( ":
\n" ); document.write( "Let d = dist between towns
\n" ); document.write( ":
\n" ); document.write( "Write a time equation; time = dist/speed
\n" ); document.write( ":
\n" ); document.write( "Actual speed time - faster time = 1 hr
\n" ); document.write( " $\"d%2F50\"$ - $\"d%2F60\"$ = 1
\n" ); document.write( "Multiply by 300
\n" ); document.write( "6d - 5d = 300
\n" ); document.write( "d = 300 mi between towns
\n" ); document.write( ":
\n" ); document.write( "Check by finding the times
\n" ); document.write( "300/50 = 6 hr
\n" ); document.write( "300/60 = 5 hrs
\n" ); document.write( " \n" ); document.write( "

\n" );
