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)
In the future, I think people won't be worried about travelling because of teleporters.It will look a big magic box or maybe it will be designed as a magic lift.In my opinion, it will be powered by solar energy and it will combine the function of a 3D map. Just think about going into a teleporter in France and choosing Vietnam as the destination. Then, 3 minutes later, you will be in Hanoi - Vietnam. That will be great.People can use it anytime and anywhere. It won't take a lot of space.I think it will replace all other vehicles and it will make people around the world closer.
I think in the future, most people will travel by flying cars.I think that it will have 2 wings so that it can fly as a plane. It will not be as big as the plane, but its speed will be higher than any other vehicles now.I think flying cars will use solar power with super thin batteries and they will use the technology called Vehicle-to-Vehicle communication, or V2V, which means cars will communicate with each other to avoid crashing. A flying car will be used for air transport, but it can also be used on the road. People can control it by touching on the control panel or they can set it in the automated control system. It can be used both in the city and in the countryside.I think flying cars will be one of the most popular means of transport in the future because they are environmentally friendly and we can avoid traffic jams by using them. However, I think we may need a sky safety system to avoid crashing.I think flying cars will be one of the most popular means of transport in the future because they are environmentally friendly and we can avoid traffic jams by using them.

1) I have lived in Bien Hoa for many years. Bien Hoa is a big and busy city. There are lots of vehicles on the road all day. There are lots of cars, buses, taxis and trucks on high ways. Vietnamese people like moving by motorbike. Almost every family has a motorbike. The traffic jam is often at about 7 a.m and 5 p.m because it’s the time when people go to work or school and come back home. There are sometimes accidents on the road. Therefore, to reduce these problems, we need to obey traffic rules to reduce accidents as much as possible.
2) All of the film I have seen Doraemon is the one I like best. Doraemon is a cartoon film. It about a robotic cat named Doraemon, who travel back in time from the 2nd to help a school boy, Nobita. The main character is Doraemon, Nobita, Shizuka, Suneo and Chaien. Doraemon is an intelligent cat, Nobita is a stupid boy, Suneo is a rich kid, Chaien is a selfish and Shizuka is a kind and pretty girl. The film bring plenty of laughter for the viewers. I love this film so much because it is interesting and it helps me relax.
Nơi tôi muốn sống là ở nông thôn.Đó là một nơi yên tĩnh và thanh bình.Có nhiều lối đi bộ và nó không gần với bãi rác.Tôi muốn sống một ngôi trường trong lành,thứ ăn trong lành,nước sạch.Tôi thích có một siêu thị và một bến xe buýt để đi lại dễ dàng.Tôi cũng muốn sống gần trung tâm thể thao(có sân vận động) bởi vì tôi là một người ham mê thể thao.
Cuối cùng để có cuộc sống khỏe đơn giản là chúng ta cần một môi trường không bị ô nhiễm .

The place I want to live is in the countryside. It is a quiet and peaceful place. There are many walkways and it is not close to the landfill. I want to live in a clean school, fresh food, clean water. I to have a supermarket and a bus station to get around. I also want to live near the sports center (there is a stadium) because I am a sports fan.
Finally, for a healthy life, we simply need an environment that is not polluted
