3 friends want to go for a hike. (Level 4)They pack enough water to last for 6 hours. 3 more people join the hike. How long will their water last now?

3 hours

Step-by-step explanation:

Because first 3 friends have water that last 6 hours when you double the amount of people you get less water, I don't speak good English to explain but you have to subtract 3 from 6 because 3 is amount of people that need water that lasts 6 hours and when you have more people you get less water s you subtract 3 from 6.

Hope you understand!
