 Thời gian ô tô đi hết quãng đường là:

  8 giờ 30 phút - 6 giờ - 15 phút = 2 giờ 15 phút

   2 giờ 15 phút  = 2,25 giờ

 Độ dài quãng đường AB là:

  52 x 2,25 = 117 ( km )

                  Đáp số: 117km

   ( 47,5 + 82,6 x 4,5 - 105 ) : 2,5

= ( 47,5 +        371,7 - 105 ) : 2,5

= (              419,2      - 105 ) : 2,5

=                           314,2       : 2,5

=                                      125,68
