\n" ); document.write( ":
\n" ); document.write( "Find the total miles driven
\n" ); document.write( "35 + 100 + 53 = 188 miles
\n" ); document.write( ":
\n" ); document.write( "Find the total time (time = dist/speed)
\n" ); document.write( "\"35%2F35\" + \"100%2F50\" + \"53%2F53\" =
\n" ); document.write( "1 + 2 + 1 = 4 hrs
