**MathMate**, Sunday, March 13, 2011 at 2:07pmNot sure why the oblique distance needs to be calculated, but that's what the question asks.

The solution is similar to the cone problem.

dx/dt=600 km h^{-1}

h=10 km

x=20 km

L=sqrt(x²+h²)

dL/dx=x/sqrt(x²+h²)

dL/dt

=(dL/dx) * (dx/dt)

=(x/sqrt(x²+h²)) * (600 km h^{-1})

=600x/sqrt(x²+h²) km-h^{-1}

=537 km-h^{-1}
