Average step is 62 steps per min.
Step-by-step explanation:
Given,
Number of steps = 775
Time = 12[tex]\frac{1}{2}[/tex] min = [tex]\frac{25}{2}[/tex] min
To find the average step
Formula
Average = [tex]\frac{Total stpes}{Time}[/tex]
So,
Average = [tex]\frac{775}{\frac{25}{2} }[/tex]
=[tex]\frac{775X2}{25}[/tex] = 62 steps per min
