Question

If a litre of water is provided for 20 people, how much for 50 people?

Answer 1

Answer:

2.5 L

Step-by-step explanation:

We use a rule of three to solve this problem, the information we have is represented as follows:

Liters       People

   1       ⇒    20

   x       ⇒    50

x represents the unknown quantity, the liters that correspond to 50 people.

The way x is found is as follows: We multiply the cross quantities and divide by the remaining quantity.

$x=\frac{50*1}{20}\\ x=2.5$

Thus, for 50 people is provided 2.5 liters of water

Answer 2

2 1/2 litres would be a reasonable amount of water assuming everyone drinks the same amount.
