You can put this solution on YOUR website!
the deceleration is ( change in speed ) / ( change in time )
\n" ); document.write( "\"+%28+40+-+100+%29+%2F+%28+3%2F60+%29+\" ( cm/min ) / min
\n" ); document.write( "Note that 3 sec = 3/60 min
\n" ); document.write( "\"+%28-60+%29+%2F+%283%2F60%29+\"
\n" ); document.write( "\"+%28-60%29%2A%28+60%2F3%29+\"
\n" ); document.write( "\"+-3600%2F3+=+-1200+\" (cm/min)/min
\n" ); document.write( "\"+-1200+\" (cm/min)/min x \"+1%2F100+\" m/cm = \"+-12+\" m/min2
\n" ); document.write( "The deceleration rate is -12 meters/minute per minute
\n" ); document.write( "
\n" );
