Question

You and a friend are knitting a scarf that will be 72 inches long. Your friend knits the first 24 inches and then gives you the scarf to finish. You expect to knit at a rate of 8 inches per day.

Answer 1

The total length is 72 inches, and our friend has already done 24 inches. Therefore we will take off 24 from 72, which gives us 48.

At a rate of 8 inches per day, we can work out how long it will take us by doing 48 divide 8, which is 6.

Therefore it would take you 6 days to finish the scarf.
