\n" ); document.write( "D=60T FOR THE TRUCK.
\n" ); document.write( "D=71(T-8/60)
\n" ); document.write( "60T=71(T-4/30)
\n" ); document.write( "60T=71T-284/30
\n" ); document.write( "60T-71T=-9.467
\n" ); document.write( "-11T=-9.467
\n" ); document.write( "T=-9.467/-11
\n" ); document.write( "T=.86 HOURS OR 51.64 MINUTES TO PASS THE TRUCK.
\n" ); document.write( "PROOF:
\n" ); document.write( "60*.86=71(.86-8/60
\n" ); document.write( "51.6=71(.86-.1333)
\n" ); document.write( "51.6=71*.627
\n" ); document.write( "51.6=51.6
