Answer:
A pump is running at a rate is 96 gal / hr.
Option (C) is correct .
Step-by-step explanation:
As given
A pump is running at a rate of 6.4 quarts per minute.
[tex]Rate = \frac{6.4\ quarts}{minute}[/tex]
As 1 quarts = 0.25 gallons
1 minute = 0.0166 hour
Now convert quarts per minute into gallons per hour .
[tex]Rate = \frac{6.4\times 0.25\ gallons}{0.0166\ hour}[/tex]
[tex]Rate = \frac{1.6\ gallons}{0.0166\ hour}[/tex]
Rate = 96.4 gal/ hr(Approx)
Best estimate of rate is 96 gal / hr.
Therefore a pump is running at a rate is 96 gal / hr.
Option (C) is correct .
