Ok !

Tổng là:

   200 +100 +60 = 360

           Đáp số:360

1 % độ dài đường là : 4560 x 1% = 45,6 ( m )

A) Ngày thứ nhất lắp được ống nước dài là : 45,6 x 32 = 1459,2 ( m )

Ngày thứ hai lắp được ống nước dài là : 45,6 x 33 = 1504,8 ( m )

B) Ngày thứ ba còn phải lắp đặt ống nước dài là : 4560 - 1459,2 - 1504,8 = 1596 ( m )

Đáp số : A) Ngày thứ nhất : 1459,2 m

Ngày thứ hai : 1504,8 m

B) Ngày thứ ba : 1596 m
