Пошаговое объяснение:

1) 45*0.5=22.5(км) -за 0.5 год.

2) 5*0.5=2.5(км) -за 0.5 год

3) 22.5+2.5=25(км) -разом

4) 25-0.5=20(км)

tasyis: як 25-0,5=20 це не правильно правильно 25-0,5=24)

>At eleven, Mark sat down at Clint's desk and looked at the dictating machine. Reggie had a client and they
needed to plan strategy for an hour. Clint typed on long paper and took the phone every five minutes.Mark got bored asked, "How did you become a secretary?" Clint turned and smiled at him. "It was an accident." Did you want to be a secretary when you were a kid?"No. I wanted to build swimming pools." "What happened?" "I don't know. I almost failed my exams school, then went to college, then went to law school." You have to go to law school to be a secretary in a law office?" No. I failed the exams in law school, and Reggie gave me a job. It's fun, most of the time."Where did you meet Reggie?"It's a long story. We were friends in law school. We've been friends for a long time. She'll probably tell you about it when you meet Momma Love, Reggie's mother. They live together, and she loves to cook for the kids Reggie represents. She makes all kinds of delicious Italian food. Everyone loves it. Reggie takes most of her clients home, especially the younger ones."The phone rang. Clint took the message and returned to his typewriter. Mark watched carefully.How did you learn to type so fast? The typing stopped, and he slowly turned and looked at Mark. He smiled, and said, ”In high school. I had this teacher who was like a sergeant. We hated her, but she made us learn. Can you type?”“A little. I’ve had three years of computer at school.”Clint pointed to his Apple next to the typewriter. “We’ve got all sorts of computers around here.” Mar looked at it, but was not impressed. Everybody had computers. So how did you become a secretary?“It wasn’t planned. When Reggie finished law school, she didn’t want to work for anybody, so she opened this office. It was about four years ago. She needed a secretary, and I volunteered. Have you seen a male secretary before?”“No. Didn’t know men could be secretaries. How’s the money?Clint laughed at this. “It’s okay. If Reggie has a good month, then I have a good month. We’re like partners.”Does she make a lot of money?“Not really. She doesn’t want a lot of money. A few years ago she was married to a doctor, and they had a big house and lots of money. Everything was lost, and she blames the money for most of it. She’ll probably tell you about it. She’s very honest about her life.“She’s a lawyer and she doesn’t want money?”“Unusual, isn’t it?”
“I’ll say. I mean, I’ve seen a lot of lawyer shows on television, and all they do is talk about money.”
