To find the average number of steps Robert climbed per minute, divide the total number of steps by the total number of minutes: \[775 \text{ steps} \div 12\dfrac{1}2 \text{ minutes}\] Let's first convert the mixed number into an improper fraction: \[12\dfrac{1}2 = \dfrac{25}{2}\] Hence, dividing the two numbers
\[\begin{aligned} 775 \text{ steps} &\div \dfrac{25}{2} \text{ minutes} \\ &= 775 \text{ steps} \times \dfrac{2}{25} \text{ steps per minute} \\ &= \dfrac{1550}{25} \text{ steps per minute} \\ &= \boxed{62}\text{ steps per minute} \end{aligned}\]
Robert climbed
\[775\] steps in
\[12\dfrac{1}2\] minutes.
