Question

A barrel had 20 liters of water. Water leaked out from the barrel at a constant rate. After 24 hours, 14 liters of water was left in the tank. How many liters of water leaked out per hour? a.0.25 b.0.50 c.1.42 d.3.14

Answer 1

let speed of water leaking out = x/h
water left in the tank after 24h=20-(speedxtime)
=20-(24x)
=14
20-24x=14
24x=6
x=1/4

Therefore, answer is (a).

Answer 2

Step
`1`

Find the amount of water that leaked out from the barrel

Subtract
`14` liters from the total of water of the barrel

so

`20-14=6\ liters`

Find the rate of liters of water leaked out per hour

Divide the amount of water that leaked out from the barrel by
`24` hours

`(6)/(24) (liters)/(hours)= 0.25(liters)/(hour)`

therefore

the answer is

`0.25(liters)/(hour)`
