1. ## Urgent (and probably basic) Math problem for Design work.

Hello

I am a graphic designer who is ridiculously bad at Math.

I need some help with a problem for a 3D piece I'm trying to complete. Its about how long it would take me to drink my body weight in Pepsi Max. (Sounds crazy I know lol). I have a bit of an addiction to it and drink a lot of it...

So...

The 3D piece is 12 stones/rocks - (in the UK we measure our weight in lbs and stones).

I weigh 12 stones, so the stones (or rocks) for my 3D piece represent my weight.
So...

There are 14lbs in a stone.

A 2 litre bottle of Pepsi Max weighs approx 4.5lbs.

I roughly drink 2 litres a day.

I need to know the following...

- How many days based on my approximates it would take me to drink my body weight.
- then I need it divided into 12 because Im writing how long it would take me to drink a stone in weight on each of the rocks. - So I would need to know both how long it would take me to drink my body weight (12 stone) and how long it would take me to drink 1 stone.

I hope this makes sense lol. Thanks to anyone who can help

2. Hello!

First let me denote W your weight in lbs

If you drink 2 liters per day and a 2 liter bottle of Pepsi Max weighs approx 4.5lbs then you got the following ratio:

$\displaystyle \frac{4.5lbs}{1(day)} = \frac{W}{x(days)}$

Just substitute your weight in lbs for W and solve the ratio for x, and you will find how many days you need to drink your own body weight

You are 12 stone. There are 14 pounds in a stone, therefore you are 12 x 14 pounds, which is 168 pounds. There are 4.5 pounds of coke in a 2 litre bottle, and you drink 2 in a day, so you drink 9 pounds in a day.

So you drink 9 pounds every day, and your target is 168 pounds... so you'd have to drink for 168/9 = 18 days and 2 thirds, so 18 days and 16 hours.

If your target is 1 stone, which is 14 pounds, then you'd have to drink 2 bottles every day for 14/9 days = 1.5556 days, which is roughly 1 day 13 hours and 20 minutes.
