let the rate of change of the bucket be expressed as:
Rate of leakage= amount of gallons/Time taken
for the large bucket:
amount of gallons = 36
rate of leakage = 0.12 gallons/hr
From the formula:
Time taken = amount of gallons//rate of leakage
Time taken = 36/0.12
Time taken = 300hr
for the small bucket:
amount of gallons = 12
rate of leakage = 0.6 gallons/hr
From the formula:
Time taken = amount of gallons//rate of leakage
Time taken = 12/0.6
Time taken = 20 hrs
we can see that the larger bucket is leaking 28
