Suppose B walks for T hours before overtaking A.
\n" ); document.write( "Thus in T hours, the distance travelled by B = 7T miles.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "By this time the total distance travelled by A would be = the distance already covered when B started + the distance covered in T hours = 2.5x4.5 + 4.5T\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since at time T B overtakes A so the total distance travelled by them at that point of time should be equal.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"7T+=+2.5%2A4.5%2B4.5T\"
\n" ); document.write( "\"2.5T+=+2.5%2A4.5\"
\n" ); document.write( "\"T=4.5\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the total distance covered by both A and B at the time T is 7 x 4.5 = 31.5 miles.
\n" ); document.write( "
\n" );
