Calling all Trig Geniuses!

For a person at rest, the velocity v (in liters per second) of airflow during a respiratory cycle (the time from the beginning of one breath to the beginning of the next) is given by
v = 0.85 sin πt/3
where t is the time (in seconds). (Inhalation occurs when v > 0, and exhalation occurs when v < 0.)

(a) Find the time for one full respiratory cycle.
sec

(b) Find the number of cycles per minute.
cycles/min
