Автор ответа: Danaamik

s1=40км t=1сағ
s2=38км
s1=40*2=80 км ; 40*3=120км ; 40*4=160км;
s2=38*2=76км ;38*3=114км; 38*4=152км;
s=40+38=78 бір сағаттан кейін
80+76=156км екі сағ кейін
120+114=234км үш сағ кейін
160+152=312 км төрт сағ кейін
v1=40км/сағ бірінші тепл жылдамдығы
v2=38км/сағ екінші теплоходттың жылдамдығы

Task 2. Read the text and fill in the table below with necessary information.
Healthy lifestyle
Today healthy lifestyle is becoming more and more popular both with the old and the young. People have become more health-conscious. They say that the greatest wealth is health. And it’s so true. The healthier we are, the better we feel. The better we feel, the longer we live.
Keeping fit and going in for sports is also important for our health. Lack of exercise in our life is a serious problem. In big cities people spend hours sitting in front of computers, TV-sets and other gadgets. We walk less because we mainly use cars and public transport. We certainly don’t have to be professional sportsmen, but we should visit fitness clubs, go jogging, walk much, swim, go cycling or roller-skating or just dance. Doctors say that regular moderate physical activity is necessary for our body because it protects us from strokes and heart diseases, flue and obesity.
We must understand the harm of bad habits for our health. Smoking, drinking or taking drugs mean serious illnesses and even death from lung cancer or liver diseases, for instance. Cigarettes kill about 3 million heavy-smokers every year. Drug addicts die very young. So I think there is no place for bad habits in a healthy way of life.
Taking a proper rest and getting enough sleep, from 8 to 10 hours daily, are also great healthy habits. Sleep is the food for our brain and the rest for our muscles. Moreover we should avoid getting nervous or worried for no reason.
Healthy way of life concerns our body, mind and soul. Healthy people live longer, they are more successful and they enjoy their life. I believe that it’s not difficult at all to follow these simple rules, and they are worth it.
