Answer:
40 days
Step-by-step explanation:
A barrel contains 50 gallons of water leaked out of the barrel at a rate of 5 gallons every 4 days at this rate
5 gallons leaked out in 4 days
50 gallons will leak out in (50x4)/5 = 10 ×4 = 40 days
It will take 40 days for the 50 gallons(1 barrel) to leak out
