You can put this solution on YOUR website!
Average speed is always: ( total distance ) / ( total time )
\n" ); document.write( "The time for the 1st mile is: \"+1+%2F+15+\" hrs
\n" ); document.write( "Let \"+t+\" = the time for the 2nd mile in hrs
\n" ); document.write( "-----------------
\n" ); document.write( "You need to solve:
\n" ); document.write( "\"+30+=+%28+1+%2B+1+%29+%2F+%28+1%2F15+%2B+t+%29+\"
\n" ); document.write( "\"+30+=+2+%2F+%28+1%2F15+%2B+t+%29+\"
\n" ); document.write( "\"+1%2F15+%2B+t+=+2%2F30+\"
\n" ); document.write( "\"+1%2F15+%2B+t+=+1%2F15+\"
\n" ); document.write( "\"+t+=+1%2F15+-+1%2F15+\"
\n" ); document.write( "\"+t+=+0+\"
\n" ); document.write( "------------
\n" ); document.write( "It is impossible, since the car can't travel the 2nd
\n" ); document.write( "mile in zero time\r
\n" ); document.write( "\n" ); document.write( "
