A barrel contained 50 gallons of oil. Oil leaked out of the barrel at a rate of 5 gallons every 2 days. At this rate, how many days did it take for all 50 gallons of oil to leak out of the barrel?
It’s 20
it took 10 days for all of the oil to leak out
50 = 10*5
so it took 10*2 = 20 days to leak out
or, to convert gallons to days,
50gal * 2days/5gal = 20 days
To find out how many days it took for all 50 gallons of oil to leak out of the barrel, we need to determine how many times 5 gallons can be subtracted from 50 gallons.
Since the oil leaked out at a rate of 5 gallons every 2 days, we can set up a proportion to solve for the number of days it took:
5 gallons / 2 days = 50 gallons / x days
To find the unknown value, x (number of days), we need to cross-multiply:
5 * x = 2 * 50
5x = 100
Dividing both sides of the equation by 5:
x = 100 / 5
x = 20
Therefore, it took 20 days for all 50 gallons of oil to leak out of the barrel.
