The heart of a man beats 75 times a minute. What is its time period?

Explanation

To find the time period of the heartbeats, we can follow these steps:

### Step 1: Understand the relationship between frequency and time period
The time period (T) is the reciprocal of the frequency (f). This can be expressed mathematically as:
\[ T = \frac{1}{f} \]

### Step 2: Determine the frequency
The frequency is defined as the number of beats per second. Given that the heart beats 75 times in one minute, we need to convert this to beats per second.
