Let x=speed of father
\n" ); document.write( "Distance of boy = rt =8(1.25)
\n" ); document.write( "Distance of father = rt = x(.25)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Distance = Distance
\n" ); document.write( "8(1.25)=.25x
\n" ); document.write( "10=.25x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Multiply both sides by 4:
\n" ); document.write( "40=4(.25x)
\n" ); document.write( "40 = x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Final answer = 40 mph\r
\n" ); document.write( "
