To find out how much Lena can knit in 1 hour, we can divide the total amount of knitting (14 square inches) by the total amount of time (3 1/2 hours).
14 square inches / 3 1/2 hours = 4 square inches per hour.
So, Lena can knit 4 square inches in 1 hour.
Now, to find out how much time it takes Lena to knit 1 square inch, we can divide the total amount of time (3 1/2 hours) by the total amount of knitting (14 square inches).
3 1/2 hours / 14 square inches = 1/4 hour per square inch.
So, the correct answer is D. 4 square inches per hour and 1/4 of an hour per square inch.
