Художник розмалював 10 однакових чашок за 2 години. За скільки годин він розмалює 15 таких чашок, якщо працюватиме з такою самою продуктивністю?

It's never late to learn. No matter how old a person is, there is always something he doesn't know. There is always space for self-improvement and education. The more you learn about life and different subjects, the more interesting person you become, the more friends you're going to have. I enjoy learning: I love reading books, discussing interesting topics with smart people and always try to do something new. Constant learning is essential for happy and productive life.

Live and learn. To my mind that's really true. We have been learning about the world since birth. Firstly, we learn to go, eat and read. Then we go to school, college or university for getting knowledge. Nevertheless, people should understand that their education shouldn't be ended when they start working. They should develop themselves all their life. It's important.
