Start with the task-warm-up :-) Change at the garment factory makes 5 t-shirts in 5 minutes on 5 machines. How many minutes does it take to change 100 t-shirts for 100 cars?Detective riddle about 4 cocktails
On a hot summer day, two friends came to a cafe and ordered 4 cold cocktails with ice. While one girl slowly savored the liquid from the glass, the second quickly drank 3 of the remaining cocktails. Half an hour later, the first one, without finishing her drink, lost consciousness and died. The police found out that all 4 cocktails were poisoned. How did the second girlfriend manage to stay alive?The problem of an electric train
When starting to solve the problem, carefully study the condition :-) The electric train moves northwards at a speed of 50 km / h. The wind blows at the same speed, but in a northeasterly direction. In which direction will the smoke from the transport pipe come out?- Surely you decided that the correct answer is 100. But this decision is mistaken: time remains unchanged, only the number of things and machines increases. The correct answer is 5 minutes.
- Everything is simple: poisoned were ice cubes in cocktails. In 3 glasses, a volley drunk by one of her friends, the ice did not have time to melt.
- If you have started a complex calculation of the trajectory of smoke, know - you are on the wrong track. In the condition of the problem, it is a question of an electric train - it is driven by the strength of the current, not the fuel: the pipe, as such, does not exist.
