The Reed family and the Mitchell family each used their sprinklers last summer. The Reed family's sprinkler was used for
20
hours. The Mitchell family's sprinkler was used for
15
hours. There was a combined total output of
1325L
of water. What was the water output rate for each sprinkler if the sum of the two rates was
75L
per hour?
Answer provided by our tutors
Let
x = the rate of Reed family sprinkler
y = the rate of Mitchell family's sprinkler
x + y = 75
20x + 15y = 1325

........
x = 40 L per hour
y = 35 L per hour
Reed family's sprinkler has a rate of 40 liters per hour.
Mitchell family's sprinkler has a rat of 35 liters per hour.
