\n" ); document.write( "The distance of the second car is,
\n" ); document.write( " $\"D%5B2%5D=%281%2F2%29%282%29t%5E2\"$
\n" ); document.write( "Find $\"t\"$ } when $\"D%5B1%5D=D%5B2%5D\"$ ,
\n" ); document.write( " $\"15t=t%5E2\"$
\n" ); document.write( " $\"t%5E2-15t=0\"$
\n" ); document.write( " $\"t%28t-15%29=0\"$
\n" ); document.write( "Two solutions:
\n" ); document.write( " $\"t=0\"$ <--- When they were both at the gas station.
