# A water hose flow at 5litre a min,how long will it take to fill a 30litres bucket?.

$6$ minutes.

#### Explanation:

• $\text{5 L = 1 minute}$

You are looking for:

• $\text{30 L = ? minute/s}$

In knowing this, you can use ratios to solve.

• $\text{5 L : 1 minute}$
• $\text{30 L : ? minutes}$

Now, multiply the $\text{30 L}$ by $\text{1 minute}$

$\text{30 min" xx "1 L" = "30 min" * "L}$

Now, divide the value by the $\text{5 L}$

("30 min" \ * \ "L") / "5 L" = "6 minutes"

A more simple method to solve this would be to see how many times the number $5$ fits into $30$. So,

$\frac{30}{5} = 6$

Therefore you need $6$ lots of $\text{5 L}$ to fill the bucket. This $6$ 'lots' is actually $6$ 'minutes'.
