# Per mil - problems

- Beer

After three 10° beers consumed in a short time there are 5.1 g of alcohol in 5 kg adult human blood. How much is it per mille? - River

Calculate how many promiles river Vltava average falls, if on section long 928 km flowing water from 1592 m AMSL to 108 m AMSL. - Crystal

Crystal grows every month 2.2 promile of its mass. For how many months to grow a crystal from weight 160 g to 311 g? - Slope of track

Calculate the average slope (in promiles and even in degrees) of the rail tracks between Prievidza (309 m AMSL) and Nitra (167 m AMSL), if the track is 77 km long. - Railways

Railways climb 7.4 ‰. Calculate the height difference between two points on the railway distant 3539 meters. - Climb in percentage

The height difference between points A and B is 587 m. Calculate the percentage of route climbing if the horizontal distance places A, B is 4.8 km. - Promile

Calculate the 4.6 ‰ of 199. - Road

Between cities A and B is route 7 km long of fall average 4‰. Calculate the height difference of cities A and B. - Drunk man

Drunkman has 1.6‰ of alcohol in the blood. How many grams of alcohol has in blood, if he have 7 kg of blood? - Height difference

What height difference overcome if we pass road 1 km long with a pitch21 per mille? - Descent of road

Road sign informs the gradient is 10.3%. Calculate the angle which average decreases. - Railway

Railway line had on 5.8 km segment climb 9 permille. How many meters track ascent? - Mountain railway

Height difference between points A, B of railway line is 38.5 meters, their horizontal distance is 3.5 km. Determine average climb in permille up the track. - Permill

How many permill is 978 from 84370? - Drunk and alcohol

One drunk measured 2.7 ‰ alcohol in the blood, another 1.75 ‰. How many grams of alcohol in the blood they had if they has 6 kg of blood? - Climb

For horizontal distance 4.9 km road rise by 6.1 m. Calculate the road pitch in ‰ (permille, parts per thousand). - Road - permille

5 km long road begins at an altitude 500 meters above sea level and ends at a altitude 521 ASL. How many permille road rises? - Beer permille

In the 5 kg of blood of adult human after three 10° beers consumed shortly after another is 6.6 g of the alcohol. How much is it as per mille? - Gold coin

Gold coin contains 964 promile pure gold, which is 7.16 g. What is the weight of coin in grams? - Lift

The largest angle at which the lift rises is 16°31'. Give climb angle in permille.
