document.write( "In t hours, the car covers the distance t times 30 miles, or  30*t miles east.\r\n" );

document.write( "The directions are perpendicular, and the current distance between the vehicles is the hypotenuse of the right triangle.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Therefore,  d =  =  =  =  = 76.158*t miles (rounded).\r\n" );
