- Tea mixture
Of the two sorts of tea for 180 CZK/kg and 240 CZK/kg, we make a mixture of 12 kg that we should prepare for 200 CZK / kg. How many kilos of each sort of tea will we need to be mixed? - Tractors
Two tractors plow the field for 4 hours together. If the first tractor plowed half of the field and then the second tractor completed the job, it would take 9 hours. How many hours does the field plow for each tractor separately? - Installed 5793
A group of fitters installed the cable line in 9 changes, and the second group completed the same task in 1/3 less time. How many shifts would the third group do the same work if, with all three groups working together, the assembly took 2 shifts? - Calculate 5770

How many percentage mixtures do we get by adding 23ml of matter to 89ml of water? - The cruise ship
The cruise ship speeds 12 km/h at a calm surface. When we sailed 45 km along the river and 45 km back, it took us exactly 8 hours. Which (constant) speed of flow of the river? - Long-distance 5737
The long-distance bus driver went 2/5 of the route length in the morning and 1/3 of this length in the afternoon. He still has 60 km to the finish. How long is the long-distance bus route? - Work
The first worker would need less than 4 hours to complete the task than the other worker. In fact, both workers worked for two hours together. Then the first worker did the remaining work himself. In what proportion should the remuneration of the workers - Filament of bulb
