meters per minute for

meters. For how many minutes does it walk?
Answer:
Ross = 15 hours
Russel = 40 hours
Step-by-step explanation:
Let Ross have used their sprinklers for x hours
Let Russell have used their sprinklers for y hours
Together they used 55 hours
x+y = 55 hours
The output of Ross is 35 liters per hour and Russell is 30 liters per hour for a total of 1725
35x + 30y = 1725
Multiply the first equation by -30
-30(x+y=55)
-30x -30y = -1650
Add this to the second equation to eliminate y
-30x -30y = -1650
35x + 30y = 1725
-----------------------------
5x =75
Divide each side by 5
x = 15
Now find y
x+y = 55
y = 55-15
y = 40
