Answer:

  • We have two variables W and N
  • W= 35 L
  • N = 25L
  • Total: 60 hrs respectfully between W and N
  • Total Water: 1700 L
  • 35W + 25N = 1700 (1)
  • W + N = 60 (2)
  • Just substitute!
  • N = 60 + W
  • 35W + 25(60 + W) = 1700
  • 35 W + 1500 + 25W = 1700
  • 60W + 1500 = 1700
  • 60W = 200
  • W = 3.33
  • Now solve for N
