Answer:

62 steps per minute.

Step-by-step explanation:

We have been given that Robert climbed 775 steps in
12(1)/(2) minutes.

To find the the average steps per minute we will divide 775 by
12(1)/(2) .

$\text{The average steps per minute}=775/ 12(1)/(2)$

Let us convert our mixed fraction into improper fraction.

$\text{The average steps per minute}=775/ (25)/(2)$

Dividing a number by a fraction is same as multiplying the number by the reciprocal of fraction.

$\text{The average steps per minute}=775* (2)/(25)$

$\text{The average steps per minute}=31*2$

$\text{The average steps per minute}=62$

Therefore, Robert climbed 62 steps per minute.
