two persons are to run a race, but one can run 10 meters per second, whereas the other can run 6 meters per second.
\n" ); document.write( " if the slower runner has a 70-meter head start, how long will it be before the faster runner catches the slower runner, if they began at the same time?
\n" ); document.write( ":
\n" ); document.write( "Let t = time required for the faster runner to overtake the slower
\n" ); document.write( ":
\n" ); document.write( "Write a distance equation: dist = speed * time
\n" ); document.write( ":
\n" ); document.write( "10t = 6t + 70
\n" ); document.write( "10t - 6t = 70
\n" ); document.write( "4t = 70
\n" ); document.write( "t = \"70%2F4\"
\n" ); document.write( "t = 17.5 seconds
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this, the faster runner has to cover 70 m more than the slower
\n" ); document.write( "1.75*10 = 175 m
\n" ); document.write( "17.5*6 = 105 m\r
