Question

Timothy uses 20 inches of yarn for knitting yarn every 5 minutes. How will he use in one hour?

Answer 1

if Timothy uses 20 inches of yarn for knitting yard every 5 minutes, then we can divide the total time in this time so in 1 hour are 60 minutues so:

$\frac{60}{5}=12$

Then he has to use:

$20\cdot12=240$
