40(t)+15(55-t)=1575
40t+825-15t=1575
25t=750
t=30
The Jenkins used their sprinklers for 30 hours, the Green's for 25!!!!!!!!!!!!!! Answer by josgarithmetic(39617) (Show Source): You can put this solution on YOUR website!
Uniform Rates situation for volume and time.
RT=V
This works just like work rates and travel rates. The same thing.
RATE TIME VOLUME
Jenkings 40 x 40x
Green 15 y 15y
TOTALS 55 1575
