It means it vibrates 30 in 60 sec.
Time period = 60/30 = 2 sec
Freq. = 1/time period = 1/2 = 0.5 Hz
Time period = 60/30 = 2 sec
Freq. = 1/time period = 1/2 = 0.5 Hz

There is simple solution for this question.
As regard to time period it is actually the time taken in one vibration of the pendulum so as the vibration is 30 and the time taken in that is 1 minutes or 60 second Thus in this case the time period will be = 60/30 = 2 second
similarly, the frequency is actually the number of vibration occurring in one second so The frequency = 1/ t = 1/2 = 0.5 Hz (t representing the time in seconds)
So the frequency will be 0.5 Hz and time period is 2 seconds
