Gọi vận tốc riêng của chiếc cano là: x(km/h) (x>3)

Vận tốc xuôi dòng: x+3

Vận tốc ngược dòng: x-3

Đổi 1giờ30phút=1,5giờ

Quãng đường cano đi từ A đến B là:

1,5.(x+3) (Km)

Quãng đường cano đi từ B về A là:

2.(x-3) (Km)

Cano đi và về trên cùng 1 quãng đường AB nên ta có phương trình:

1,5.(x+3)=2.(x-3)

1,5x+4,5=2x-6

1,5x-2x=-6-4,5

-0,5x=-10,5

x=21(thoả mãn)

Vậy vận tốc riêng của cano là 21km/h

Thay x=21 vào 2.(x-3) ta có:

2.(21-3)=2.18=36(thỏa mãn)

Vậy quãng đường AB dài 36km
