Period is defined as the time to make one oscillation. Can you find the period now?
Frequency is the amount of oscillations in one second. It is also the inverse of period.
f=\frac1T
T = period
f = frequency

If she started counting at the first heartbeat, then she only counted 75 periods during the 1 minute.
