Algebra.Com's Answer #380571 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! An object is moving at a speed of (3+2^(1/2)) ft/s. How long will it take the object to travel 20 ft? \n" ); document.write( "------------------------ \n" ); document.write( "time = distance/rate \n" ); document.write( "---- \n" ); document.write( "time = 20 ft/(3+sqrt(3))(ft/sec) \n" ); document.write( "---- \n" ); document.write( "= [20(3-sqrt(3))]/[(3+sqrt(3))(3-sqrt(3)] \n" ); document.write( "----- \n" ); document.write( "= [20(3-sqrt(3)]/[9-3] \n" ); document.write( "----- \n" ); document.write( "= (10/3)(3-sqrt(3)) \n" ); document.write( "--- \n" ); document.write( "= 10 - (10/3)sqrt(3) \n" ); document.write( "======================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "======================== \n" ); document.write( " |
