Question 82537
Good old Mr Pythagoras raises his head once again.
You have a right angled triangle with one side of 35 km, one side of 65 km and the third side being the hypotenuse of the triangle.
{{{c^2=a^2+b^2}}}
{{{c^2=35^2+65^2}}}
{{{c^2=1225+4225}}}
{{{c^2=5450}}}
{{{c=sqrt(5450)}}}
c = 73.8 km
