how fast is it.........

if a small plane with glide ratio 7:1
glide ratio 7:1 means plane moves forward 7 feet
for every 1 foot altitude (height) lost.

so if a plane at 10000 feet in air has its engine shut off.
how fast will it be moving forward when the plane touches the ground.

dumbass I said with engine shut off.
you should have assumed stall speed starting at 0 km/hr
which is not likely or posible.

but its just a simple math problem.
you also want me to mention the drag coefficient
and wind velocity and weight of the plane,
and the angle of the stall.
dammit It was a simple question.
