Algebra.Com's Answer #64055 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! Martin leaves home at 9 a.m. bicycling at a rate of 24mi/hr. Two hours later,John leaves,driving at the rate of 48mi/hr.At what time will John catch up with Martin? \n" ); document.write( ": \n" ); document.write( "Let x = time (in hrs) that M is on the road \n" ); document.write( "Then \n" ); document.write( "(x-2) = time J is on the road, when he catches up \n" ); document.write( ": \n" ); document.write( "We know when this happens they will have traveled the same distance. \n" ); document.write( "We can make a simple equationn from this fact: Dist = speed * time \n" ); document.write( ": \n" ); document.write( "J's dist = M's dist \n" ); document.write( "48(x-2) = 24x \n" ); document.write( "48x - 96 = 24x \n" ); document.write( "48x - 24x = +96 \n" ); document.write( "24x = 96 \n" ); document.write( "x = 96/24 \n" ); document.write( "x = 4 hrs; from 9 am would be 1 pm when J catches up with M \n" ); document.write( ": \n" ); document.write( ": \n" ); document.write( "Check solution using distance, J's time is 2hrs: \n" ); document.write( "48(2) = 24(4) \n" ); document.write( ": \n" ); document.write( "Not that hard, right? \n" ); document.write( " |
