Так как на велосипеде он двигался в два раза быстрее, то , соответственно, времени он потратил в два раза меньше = 2 часа

Read my Lips!
Forget about fortune tellers and horoscopes. The shape of a person’s lips can say a lot about them. The 5.000-year-old art of face reading is gaining popularity. So, take a look at the shape of someone’s lips to find out about their personality….
People with full lips are usually responsible. You can always trust them to do what you ask them to do. They are also decisive; they make decisions quickly. On the other hand, they tend to be rather bossy. They like telling other people what to do!
People who have thin upper lip and full lower lip are energetic. They work very hard and like participating in a lot of activities. They are ambitious as well; they want to be successful in life. However, these people tend to be self-centered. They seem to only care about themselves and they sometimes forget about other people’s feelings.
People with thin lips are determined; they know what they want and they do all they can to get it. They are careful people who do their work with a lot of atten-tion and thought. However, they tend to be reserved; they don’t like showing their feelings or expressing their opinions. They can also be mean; they don’t like sharing things or spending money.
People who have lips with down-turning corners are very generous. They love giving things to other people and helping them. They are also intelligent and understand difficult subjects quickly and easily. On the other hand, they can be sensitive at times; they get upset easily, so be careful of what you say to them.
