Mrs rivers can grade 8 math test in 10 minutes .what is the teachers unit rate in test per minute?

 " 0.8 test per minute " .

Step-by-step explanation:

8 tests per 10 minute = ? tests per 1 minute ;

Note:  Unit rate ;  is expressed as:  "per 1 minute" ;  

      {that is:   "per 1 unit of measurement" ;

              or:  "per single unit of measurement" .}.

   "8 tests per 10 minutes"  =  "8/10 test" per " 1 minute" ;

       "8/10"  =  " 8 ÷ 10 " =  "0.8 " ;  

     So:   " 0.8 tests per 1 minute" ;

that is:

            " 0.8 tests per minute " .

Hope this answer — and explanation — is helpful .

    Best wishes!
