Quãng đường dài số km là:

`40 xx (10 - 7) = 120 (km) `

Thời gian ô tô đi là:

`120 : 50 = 2,4` (giờ)

Thời điểm oto xuất phát là:

`10 ` giờ `- 2,4` giờ `= 7,6` giờ `= 7` giờ `36` phút

Đáp số: ...

                         Giải:

Thời gian xe máy đi hết quãng đường AB là: 10 giờ - 7 giờ = 3 giờ

Quãng đường AB dài là: 40 x 3 = 120 (km)

Thời gian ô tô đi hết quãng đường AB là: 120 : 50 = 2,4 (giờ)

2,4 giờ = 2 giờ 24 phút

Thời điểm xe ô tô xuất phát là: 10 giờ - 2 giờ 24 phút = 7 giờ 36 phút

Đáp số: Thời gian xe máy xuất phát là 7 giờ

             Thời gian xe ô tô xuất phát là 7 giờ 36 phút 

Điện thoại của AB tối giản là như  nào em?

\(\dfrac{1}{5}\times\dfrac{3}{4}+\dfrac{1}{5}\times\dfrac{5}{4}-\dfrac{1}{5}\\ =\dfrac{1}{5}\times\left(\dfrac{3}{4}+\dfrac{5}{4}-1\right)\\ =\dfrac{1}{5}\times\left(2-1\right)\\ =\dfrac{1}{5}\times1\\ =\dfrac{1}{5}\)

`1/5 xx 3/4 + 1/5 xx 5/4 - 1/5`

`= 1/5 xx (3/4 + 5/4 - 1) `

`= 1/5 xx (8/4 - 1) `

`= 1/5 xx (2 - 1) `

`= 1/5 xx 1`

`= 1/5`
