Consider right triangles ADB and ADC in the figure, right angle D.

By alternate transversals ABD=63° and ACD=11°.

$\tan 63 = \frac 8 y$

$\tan 11 = \frac 8{x+y}$

$y = (8)/(\tan 63)$

$x = -y + (8)/(\tan 11)$

$x = (8)/(\tan 11) - (8)/(\tan 63)$

$x \approx 37.08 \textrm{ meters}$

That's in one second, so

Answer: 37 meters per second
