đổi : 8 phút 12 giây = 492 giây = \(\dfrac{41}{300}\) giờ

quãng đường mà xe lửa toa đầu vào đường hầm cho tới lúc toa cuối ra khỏi đường hầm là : 

 \(48\cdot\dfrac{41}{300}=\dfrac{164}{25}=6,56\left(km\right)\)

đổi : 6,56km = 6560 m

vậy quãng đường hầm dài là : 6560 - 120 = 6440 (m)

called 

My name's Hannah and I'm 25 years old. I've got a daughter ..(36)……Nicole. She's nearly three now. I live in a small flat …..(37)……. the city centre. It isn't a nice place to live. It's very noisy and dirty and there is ..(38)…… for Nicole to play.

I want to move out of the city and live in the countryside. But it's very expensive to live there. I will need to earn enough money to buy a house. There aren't …(39)… flats for sale in the small villages near here. I will need to buy a car too.

I really like spending time with Nicole. In the evening, I work as a cleaner. I clean people's houses. Nicole comes with me. She plays ..(40)….. with her toys while I work.
