Answer:
62 steps per minute.
Step-by-step explanation:
We have been given that Robert climbed 775 steps in [tex]12\frac{1}{2}[/tex] minutes.
To find the the average steps per minute we will divide 775 by [tex]12\frac{1}{2}[/tex].
[tex]\text{The average steps per minute}=775\div 12\frac{1}{2}[/tex]
Let us convert our mixed fraction into improper fraction.
[tex]\text{The average steps per minute}=775\div \frac{25}{2}[/tex]
Dividing a number by a fraction is same as multiplying the number by the reciprocal of fraction.
[tex]\text{The average steps per minute}=775\times \frac{2}{25}[/tex]
[tex]\text{The average steps per minute}=31\times2[/tex]
[tex]\text{The average steps per minute}=62[/tex]
Therefore, Robert climbed 62 steps per minute.
