(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Ok so im given that a pendulum swings 41.35 seconds in 20 cycles. I have to find the frequency of that pendulum

2. Relevant equations

i know that f=1/T where T is period b/c frequency and period are reciprocal to each other.

i also know that f = N/t where t is the time for i think 1 cycle? but i dont know N

3. The attempt at a solution

Im not given Period so i have no idea how to solve for this. Please help! and please be specific on how u got your answer. Thx
