Ответ:

1800÷3=600 - відер за 1 годину.

600÷5=120 - відер викачає 1 насос за 1 годину.

120×4=480 - 4 насоси за годину.

480×4=1920 - 4 насоси за 4 години

Ответ:

1920 вёдер воды

Пошаговое объяснение:

1) 1800 : 3 = 600 (вёдер) - воды качают за 1 час 5 насосов

2) 600 : 5 = 120 (вёдер) - воды качает за 1 час 1 насос

3) 120 * 4 = 480 (вёдер) - воды накачает за 4 часа 1 насос

4) 480 * 4 = 1920 (вёдер) - воды накачает за 4 часа 4 насоса

Task 1. Answer the questions. 1 Why is it important for teenagers to understand the different paths they can take in the world of work? 2 What are some examples of gig economy jobs that teenagers can explore? 3 Why are communication skills important in any career path? 4 Why are time management skills important in any career path?

The world of work can be a daunting and exciting prospect for teenagers. As you start to think about your future, it's important to understand the different paths you can take and the skills you will need to succeed.

One of the biggest changes in the world of work is the rise of technology. Many jobs now require a basic understanding of computer systems and digital tools, so it's important to develop these skills early on. You can start by learning basic coding languages or taking online courses in technology-related fields.

Another trend to be aware of is the gig economy, where workers take on short-term, flexible jobs. This can be a great way to gain experience and build your skills, but it also means that you will need to be adaptable and comfortable with uncertainty. Freelancing, tutoring, and pet-sitting are just a few examples of gig economy jobs that you can explore.

Internships and volunteer work are also excellent ways to gain experience and make

connections in your desired field. Even if you don't get paid, the experience and

connections you make can be invaluable in the long run.

However, no matter what career path you choose, there are certain skills that will always be important. These include communication, problem-solving, and time management. Developing these skills through extracurricular activities and volunteering can help you stand out from the competition and succeed in any field.

In conclusion, the world of work is changing rapidly, and it's important for teenagers to stay informed and prepared. Developing technology skills, exploring the gig economy, and gaining experience through internships and volunteer work are just a few ways to prepare for the future. However, no matter what path you choose, strong communication, problem-solving, and time management skills will always be essential. СРОЧНО ДАМ 50 БАЛЛОВ
