- Map distance
On a map with a scale of 1:250000, the distance between the two mountain peaks is 32 mm. What is the actual length in km? - A cold front
At 1:00 PM, the temperature was 46 degrees. A cold front then moved in and decreased the temperature by 12 degrees per hour. What was the temperature at 6:00 PM? - Eight hours
Brigadier Franta ties a sheaf of hay in 20 minutes. Lujza, at the same time, only a quarter. How many sheaves will they tie together in 8 hours? - Wave parameters
Calculate the speed of a wave if the frequency is 336 Hz and the wavelength is 10 m. - Bus travel time
The bus goes 9 km in 7 minutes. How long will it take to go 35 km (in hours)? - Resistance of the resistor
The resistor terminals have a voltage of 20 V, and a current of 5 mA is passed through. What is the resistance of the resistor? - Car distance
The car will travel 28 km in one hour. How far will it travel in two and a half hours? - Water drainage
1000 l of water will drain in one outflow in 4 hours. How many hours will it take for 3 drains to empty 9000 l? - Jet distance
