Question 152461
After operating for 40 minutes, a small pump has removed 60 gallons of water from a 6000-gallon swimming pool. There is a linear relationship between the gallons of water V remaining in the pool and the pumping time t in minutes. Find the equation for this relationship.
:
Find the pumping rate from the statement:
"After operating for 40 minutes, a small pump has removed 60 gallons of water"
{{{60/40}}} = 1.5 gal/min
:
The equation:
V = 6000 - 1.5t
