Robert climbed 775 steps in 12 1/2 minutes. how many steps did he average per minute

The sense of "rate " being used is "a quantity, amount, or degree of something measured per unit of something else". This is what is asked in this problem. TO calculate, we divide the number of steps to the time it takes.

Steps/min = 775/12 1/2 = 62 steps per minute

Hope this answers the question. Have a nice day.
