Question

3 friends want to go camping and they pack enough water to last for 6 days. Just as they are about to leave they are joined by 3 more people. How long will their water last now?

Answer 1

Answer:

just 3 days more......

Answer 2

Answer:

3 days

Step-by-step explanation:

Firstly you work out how many days the water would last 1 person to do this you multiply 3 by 6 (there is 3 friends and the water is set to last 6 days)

3x6 = 9

so the water would last 1 person 9 days

But we need to work out how much it would last 9 people...

to do this you divide 9 by the added number of people... 3

so 9 divided by 3 = 3

the answer is 3 days
