Algebra.Com's Answer #645885 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! The remaining time is 4.5 hours. The driver has a rate of 55 mph, so the distance is less than or equal to 55*4.5=247.5 miles. It might be less than that if d is less. \n" ); document.write( "a above shows that \n" ); document.write( "247.5/55=4.5+3.5 must be less than or equal to 8. \n" ); document.write( "the one that should be excluded is c, but there 4.5-3.5 is less than or equal to 8, and that would never be close to 8, whereas in 8, if the driver continues at this rate, it will be exactly 8. \n" ); document.write( " \n" ); document.write( " |
