Problema Solution
2 people are filling up a 35 gallon fish tank 1 person in a one gallon jugs of water into a tank every 2 minutes the other person and is a 2 gallon jugs of water into the take every 3 minutes how long would it take to fill up the tank
Answer provided by our tutors
let 'x' represent the amount of minutes taken to fill up the 35 gallon tank
in 'x' minutes, a one gallon jug every 2 minutes provides this much water: (x / 2)
and a two gallon jug every 3 minutes provides this much water: 2*(x/3)
we solve for the length of time, x, require to provide 35 gallons:
35 = x/2 + 2x/3
and we have x=30
it will take 30 minutes to fill up the tank in this manner; this is an acceptable answer since 3 minutes and 1 minute both divide evenly into 30 minutes and therefore both the one gallon and the two gallon jugs are added to the tank in the final minute
