Road

Between cities A and B is route 13 km long of stúpanie average 7‰. Calculate the height difference of cities A and B.

Correct result:

h =  91 m

Solution:

s=13 km m=13 1000  m=13000 m q=7/1000=71000=0.007  A=180πarctan(q)=180πarctan(0.007)0.4011  h=s sinA=s sin0.401063905967 =13000 sin0.401063905967 =13000 0.007=90.99777=91 m  h1=13 7=91 m  h1h
