The total work is
(mass of the elevator, kg) x (9.8 m/s²) x (9.0 m) Joules .

Not what I'd call 'fast' at all.
Speed = (distance covered) / (time to cover the distance) .
Speed = (5 meters) / (10 seconds)
<em>Speed = 0.5 meter per second</em> .
That's like about 1.1 mile per hour .
Normal walking speed is considered to be around 1.4 m/s ... about 3.1 mph, or 14 meters in 10 seconds.
I've got a grandson who hasn't even turned 1 yet. He crawls and doesn't walk, but if you only cover 5m in 10s, he'd leave you in the dust pretty quick.
