Question

the ramirez family and the gonzales family each used their sprinklers last summer. The Ramirez family sprinkler was used for 35 hours.the gonzales Family sprinkler was used for 15 hours. There was a combined total output of 1825 liters of water. what was the water output rate for each sprinkler of the sum of the two rates was 75 liters per hour

Answer 1

Let the two water rates be R_R and R_G. Then the water used by each family is given by hours x rate.

 

Write an equation using those amounts and the total water usage, 1825 liters.

 

You should also be able to write another equation for the total water rate of 75 l/hr.

 

Can you solve it from there?
