Answer

Explanation:

Step1: Convert quarts to liters

First, convert 84 quarts to gallons. Since 1 gallon = 4 quarts, the number of gallons in 84 quarts is $\frac{84}{4}=21$ gallons. Then, convert gallons to liters. Given 1 gallon = 3.785 liters, the number of liters in 21 gallons is $21\times3.785 = 79.485$ liters.

Step2: Convert hours to weeks

The time is 9.5 hours. First, convert hours to days. Since 1 day = 24 hours, the number of days in 9.5 hours is $\frac{9.5}{24}$ days. Then convert days to weeks. Since 1 week = 7 days, the number of weeks in $\frac{9.5}{24}$ days is $\frac{9.5}{24\times7}$ weeks.

Step3: Calculate the rate in liters per week

The rate $r$ in liters per week is given by the formula $r=\frac{79.485}{\frac{9.5}{24\times7}}$. [ \begin{align*} r&=79.485\times\frac{24\times7}{9.5}\ &=79.485\times\frac{168}{9.5}\ &=79.485\times17.68421\ &\approx1405 \end{align*} ]
