Algebra.Com's Answer #92846 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! the time(T) required to perform a some distance by car is inversely proportionnal to the velocity(V). knowing that a some distance has been covered in 6 hours has an average speed of 90 km\h, how fast would it take to make this ride same journey in 5 hours \n" ); document.write( "---------------- \n" ); document.write( "T =k/V \n" ); document.write( "Need to find \"k\": \n" ); document.write( "6 = k/90 \n" ); document.write( "k = 540 \n" ); document.write( "------------ \n" ); document.write( "Equation for your problem: \n" ); document.write( "T = 540/V \n" ); document.write( "---------- \n" ); document.write( "If the ride takes 5 hours you get: \n" ); document.write( "5 = 540/V \n" ); document.write( "V = 540/5 \n" ); document.write( "V = 108 km/h \n" ); document.write( "================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
