Well, the point of asking questions isn’t to just get the answer handed to you.

You get hints to lead you through - giving you the answer doesn't help. Maybe read the rules yourself?

I didn't want the answer handed to me, I just wanted help in the question

So how long would 1 man take to dig a hole 3 metres deep?

Are you trying to prove a point or do you genuinely want to help. If it's the latter then my answer is I don't know because I don't understand where to start

Rude! I'm trying to help

Think - will it take one man a longer or a shorter time than 6 men?

longer so if we do the ratio between 6 men who took 4 days and 1 man who took x days then its 6x4 which is 24 which means 1 man took 24 days (Is this right?) . Also I didn't mean to be rude I thought you were making fun of me

I'm doing GCSEs myself.
6 men = 4 days
divide by 6 to get one man and then times by 6 to get the number of days it would take
1 man = 24 days
now do the same for 10 men. it's kinda like you're doing the inverse

Then you want the hole 7 metres deep - so you need to think about that.

I tend to get people to think about a hole one metre deep first - that will take less time so ....

yes I did that I got (7x4)/3 = 56 then I used this info to work out the ratio of 1 man who took 56 days to dig a 7m hole with the ratio of 10 men who took x days to dig a hole 7m deep. I eventually got 5.6 by dividing 56 days on the 10 menThank you all so much
