Total time = \"+12+%2B+300+%2B+400+=+712+\" sec
\n" ); document.write( "Total distance = \"+100+%2B+1000+%2B+500+=+1600+\" m
\n" ); document.write( "Average speed is [ total distance ] / [ total time ]
\n" ); document.write( "\"+1600%2F712+=+2.2472+\" m/sec
\n" ); document.write( "------------------------------------
\n" ); document.write( "\"+100%2F12+=+8.333+\" m/sec
\n" ); document.write( "\"+1000%2F300+=+3.333+\" m/sec
\n" ); document.write( "\"+500%2F400+=+1.25+\" m/sec
