250

Explanation:  

Let's call the number of standard downloads S and the number of high-quality downloads H.  

For number of downloads:  

(1) H = 3S  

For downloaded size:  

(2) 4.4H + 2.1S = 3825     Substitute H in Equation (2)  

4.4 × 3S + 2.1S = 3285  

    13.2S +2.1S = 3825     Combine like terms  

              15.3S = 3825  

                    S = 250

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
