Today, I am at home. It is Saturday morning and it is very cold. Last month, my family and I were on

holiday in Canada. The weather is fantastic! It is really hot and sunny. We were happy then

The last vacation was great, but now I am

happy to be back. It is nice to be with all my friends.

Twenty years ago, there were no cars on the street where I lived.There was only one bakery in the whole town. There was no Internet at that time, so we sent letters to communicate with friends and family who lived far away. I didn't like to go to school far away because, the bus stop was from my house. Now, the street in front of my house.

There are many cars and buses. There are also many shops and there is big a department store right next to my house!

Yesterday, there was police blockade on the road because there was a robbery. I was

very scared and my parents worried because it happened in front of my house. This

morning, I heard that the robber got caught and I am glad that finally our place is safe!

1) 480-360=120(км)

2) 120 км: 120:2=60(км/ч)

3) 360:60=6(ч)

4) 480:60=8(ч)

Обьяснение:

1) Для начала мы можем найти расстояние, которое проехал второй автомобиль после остановки первого: 480-360=120(км)

2) Теперь, зная, что второй автомобиль был в пути на 2 часа больше, чем первый, можно найти скорость, ведь за 2 часа он проехал 120 км: 120:2=60(км/ч)

3) Зная, что скорость у обеих авто была одинаковой и не менялась, можно найти время пути каждого автомобиля:

№1 = 360:60=6(ч)

№2 = 480:60=8(ч)

P.S. Т.к. в условии сказано, что первый автомобиль был в пути на 2 часа меньше, мы можем увидеть, что в решении первый автомобиль ехал 6 часов, когда второй - 8, тоесть первый был в пути на 2 часа меньше.

ответ: на 8
