Algebra.Com's Answer #615286 by addingup(3677)![]() ![]() You can put this solution on YOUR website! Distance= rate x time (rate is another word for speed) \n" ); document.write( "For John, we know the distance (300mi) and the time (9hrs) so we need to find the rate: \n" ); document.write( "We divide both sides of the equation by time: \n" ); document.write( "Distance/time= rate \n" ); document.write( "300/9= 33.33 miles per hour is John's speed. \n" ); document.write( "---------------------- \n" ); document.write( "Alex travels twice as far at 1/3 the speed, so Alex goes 600 miles at 11.11mph: \n" ); document.write( "Distance= rate*time Divide both sides by rate \n" ); document.write( "distance/rate= time \n" ); document.write( "600/11.11= 54hours; 54/24= 2 days and 6 hours \n" ); document.write( "Alex starts at 12+3 at 3pm and finishes 2 days later at 9pm \n" ); document.write( " |
