Final answer:
To find the number of square inches knit per hour, use the equation Rate = Amount/Time. To find the number of hours spent knitting per square inch, use the reciprocal of the rate.
Step-by-step explanation:
To find the number of square inches knit per hour, we can use the equation: Rate = Amount/Time. In this case, Lena can knit 14 square inches in hours, so the rate is:
Rate = 14 square inches/ hours
To find the number of hours spent knitting per square inch, we can use the reciprocal of the rate:
Rate = 1/(14 square inches/ hours)
To simplify the rate, we divide the numerator and denominator by 14:
Rate = 1/(1 square inch/ (14/ hours))
Rate = 1/(1/ (14/ hours))
Rate = 1/(14/ hours)
Rate = hours/14 square inches
