5.5 bits and 7.3 bits are the hard days of a high school student.

Here’s what a child’s unhealthy mind has to face:

Bogdanovich M.V. Mathematics: A textbook for 4 (3) classes. Education in 1995.

Chapter 18 (s. and 153). From two settlements, the distance between which is 90 km, two cyclists traveled simultaneously to meet each other. The first of them moved at a speed of 14 km / h. In how many hours will the cyclists meet?

Item 944 (s. and 168). In the school dining room, 24 kg of wheat was consumed for cooking for breakfast. 36 kg of wheat was used to prepare lunch. How much food is left in the dining room?

The candidate of science and the one crying over the task.
