A row of beans is planted at the beginning and end of a garden that is 30 feet long. A row of beans is also planted every 15 inches along the length of the garden. How many rows of beans are there in all?

a. 20 rows

b. 24 rows

c. 25 rows

d. 30 rows

Answer: c. 25 rows

A 30 feet long garden planted in a row beans every 15 inches will make 24 rows. But since a row of beans is planted at the beginning, we add one row making it 25 rows in all.

Solution:

30 ft = 30 (12) = 360 inches

360/15 inches = 24

24+1

25
