To calculate Steps Per Minute (SPM):
\[ SPM = \frac{D}{SL \times T} \]
Where:
Steps per minute is defined as the total number of steps a person takes on average per minute based on their stride length.
Let's assume the following values:
Step 1: Use the steps per minute calculation formula:
\[ SPM = \frac{1000}{0.75 \times 20} \approx 66.67 \text{ steps/minute} \]
The Steps Per Minute is approximately 66.67 steps/minute.
