Question

A barrel contained 70 gallons of water. Water leaked out of the barrel at a rate of 5 gallons every 3 days.

At this rate, how many days did it take for all 70 gallons of water to leak out of the barrel?

Answer 1

42 days

Explanation:

Given

`Gallons = 70`

Leakage = 5 gallons in 3 days

Required

Determine the number of days it finish leaking out

The scenario can be represented as:

5 gallons = 3 days

and

70 gallons = x

Where x represents the number of days to leak out 70 gallons

Cross Multiply:

`5 * x = 3 * 70`

`5 x = 210`

Divide both sides by 5

`x = (210)/(5)`

`x = 42`

Hence, it'll take 42 days
