Problema Solution

You are knitting a scarf for you best friend and want to have it finished by 6:00pm. You want the scarf to be 60 inches long when it is complete. At 1:00p.m you have already knit 15 inches of the scarf, and you estimate that from this point on, you can knit at the rate of 1/4 inch per minute.

1) What time will it be when you complete the scarf?

Answer provided by our tutors

Rate = 0.25in/min

Remaining distance  = 60in - 15in = 45in.

Distance = Rate * Time

Time = Distance/Rate

Time = 45in/ 0.25in/min = 180 min * 1h/60min = 3hr

Start Time = 1:00pm + 3hr = 4:00pm
