a leak I a storage tank caused 600 gallons of water to drain out in 70 minutes. What is the average rate of change in the tank water level? (round to the nearest hundredth)

Respuesta :

We have a drainage of 600 gal in 70 minutes.

We can calculate the average rate of change, in gal/minute, dividing the total volume drained by the time it took:

[tex]r=\frac{600\text{ gal}}{70\min}\approx8.57\frac{gal}{\min }[/tex]

Answer: the average rate of change is 8.57 gal/min.
