Robert is in charge of a community swimming pool. each sprig he drains it in order to clean it. then he refills the pool, which holds 120,000 gallons of water. robert fills the pool at a rate of 10 gallons each minute. what is the rate at which robert will fill the pool? is it constant? write an equation for the direct variation.

The pool holds 120,000 gallons of water.

Robert fills the pool at a rate of 10 gallons each minute.

That means for filling 120000 gallons, he will need = = 12000 minutes

If we convert this to hour, then in 1 hour, = 600 gallons  can be filled.

So, the rate in gallons per hour =   = 200 gallons per hour.  

Therefore, the rate at which Robert will fill the pool is 200 gallons per hour.

Yes the rate is constant.

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
