Answer:
Step-by-step explanation:
Given
Rate of Long family's sprinkler is 25 L/hr
rate of Harris family's sprinkler is 35 L/hr
Total time for which sprinkler is used =55 hr
Let long family run their sprinkler for x hr
therefore Harris family time=55-x
Total volume collected=1625 L
thus
![25\times x+35\times (55-x)=1625](https://tex.z-dn.net/?f=25%5Ctimes%20x%2B35%5Ctimes%20%2855-x%29%3D1625)
25x+1925-35x=1625
1925-1625=10x
300=10x
x=30 hr
long family used for 30 hr and Harris family used for 20 hr
