Tiffany is filling her daughter's pool with water for a hose.she can fill the pool at a rate of 1/10 gallons/second. if the pool holds 50 gallons, how long will it take to fill the pool?
Let
x -----> the number of seconds
y ----> the number of gallons
we know that
the linear equation is equal to
y=(1/10)x
For y=50 gal
substitute
50=(1/10)x
solve for x
x=500 sec
Convert to minutes
500/60=8.33 min
or 8 min and 20 sec
