Answer :
Answer: the water is being pumped at the rate of 65 gallons per minute
Step-by-step explanation:
The volume of water in the tank, V, in gallons, is given by the equation:
V(t) = 65t + 280,
where
t is the time, in minutes,
v is the volume of the water in gallons.
The volume of water being pumped is a function of time. It is a Linear equation and it takes the form of the slope intercept equation, y = mx + c
Where m is the slope and
c is the intercept. Comparing both equations, the slope in the given equation is 65.
Slope means the rate of change in y with respect to x. So it means that the volume of water in the tank in gallons is increasing at a rate of 65 gallons per minute.
