A pendulum requires 2 seconds to complete a cycle, which consists of a complete
back-and-forth oscillation (extreme point to equilibrium to opposite extreme point
back to equilibrium and finally to the original extreme point). As long as the
amplitude of the motion (the amplitude is the distance from the equilibrium position
to the extreme point) is small compared to the length of the pendulum, the time
required for a cycle is independent of the amplitude.
How long does it take to get from one extreme point to the other, how long from an
extreme point to equilibrium, and how long to go from extreme point to equilibrium
to opposite extreme point and back to equilibrium?
1sec
.5sec
1.5sec

What reasonable assumption did you make to arrive at your answers?

From one extreme to the other would be half cycle or 1sec.
From an extreme to equilibrium would be half that or .5sec.
From extreme to equilibrium, equilibrium to extreme and extreme to equilibrium would
be 1.5sec.
