# River

Calculate how many promiles river Dunaj average falls, if on section long 957 km flowing water from 1454 m AMSL to 101 m AMSL.

Result

p =  1.41

#### Solution:

$h_{1}=1454-101=1353 \ \text{m} \ \\ h_{2}=957 \ km \rightarrow m=957 \cdot \ 1000 \ m=957000 \ m \ \\ \ \\ s=\dfrac{ h_{1} }{ h_{2} }=\dfrac{ 1353 }{ 957000 } \doteq \dfrac{ 41 }{ 29000 } \doteq 0.0014 \ \\ \ \\ p=1000 \cdot \ s=1000 \cdot \ 0.0014 \doteq \dfrac{ 41 }{ 29 } \doteq 1.4138 \doteq 1.41 \ ‰$ Our examples were largely sent or created by pupils and students themselves.
