A car has a speed 12 miles/hour faster than a truck. If the car travels 175 in the same time the truck travels 145 miles, what is the speed of the truck?\r
\n" ); document.write( "\n" ); document.write( "let ths speed of the truck be x\r
\n" ); document.write( "\n" ); document.write( "the car's speed will be x+12 mph\r
\n" ); document.write( "\n" ); document.write( "Time taken by truck to travel 145 miles = 145/x\r
\n" ); document.write( "\n" ); document.write( "Time taken by car to travel 175 miles = 175/ x+12\r
\n" ); document.write( "\n" ); document.write( "These times are same\r
\n" ); document.write( "\n" ); document.write( "145/x= 175 / x+112\r
\n" ); document.write( "\n" ); document.write( "145(x+12) = 175x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "145x+1740 = 175x\r
\n" ); document.write( "\n" ); document.write( "175x-145x= 1740\r
\n" ); document.write( "\n" ); document.write( "30x=1740\r
\n" ); document.write( "\n" ); document.write( "x=58 which is the speed of the truck\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
