# AMSL and skiing

Tomas skis from point A (3200m above sea level to place B. Hill has 20% descent. The horizontal distance between the start and finish is 2,5km. At what altitude is point B?

Result

B =  2700 m AMSL

#### Solution:

$A = 3200 \ m \ \\ p = 20 \% = \dfrac{ 20 }{ 100 } = 0.2 \ \\ x = 2.5 \ km = 2.5 \cdot \ 1000 \ m = 2500 \ m \ \\ \ \\ B = A - p \cdot \ x = 3200 - 0.2 \cdot \ 2500 = 2700 = 2700 \ \text{ m AMSL }$

Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
