Question

If it takes 10 grannies 10 minutes to knit 10 socks, how long would it take 100 grannies to knit 100 socks

Answer 1

Step-by-step explanation:

Given  

If it takes 10 grannies 10 minutes to knit 10 socks, how long would it take 100 grannies to knit 100 socks

So work = grannies x time x rate

         10 = 10 x 10 x R  

     So R = 1/10

Now we need to find time using rate.

So work = no of grannies x time x rate

     100 = 100 x T x 1/10

So 10 T = 100

So T = 10
