The code first calculates the altitude (distanceA) then waits for one second and then calculates altitude once again (distanceB).
It calculates the velocity of the elevator by the formula velocity = (difference in altitude)/time.
Time is one second.

The altimeter waas tested in two different elevators - Luddy Hall and Geology Building.
The observations are as follows:

Luddy Hall Up   
Time (s)    Velocity (m/s)
1           0.2500
2           0.1250
3           2.1250
4           2.4375
5           2.5625
6           0.7500
7           0.0625

Luddy Hall Down 
Time (s)    Velocity (m/s)
1           0.0625
2           0.6250
3           1.3750
