A weed called the boomstar vine is known for growing at a very fast rate. It can grow up to 0.5 feet per day.
A. How fast in inches per day can the boomstar vine grow up to?

B. How fast in inches per hour can the boomstar vine grow up to?

Answer 1

A) 1 foot = 12 inches. If the vine grows a half of a foot per day, then in inches that would be half of 12 which is 6 inches.

B) A day is equivalent to 24 hours. If the vine grows 0.5 feet under a period of 24 hours then, the vine can grow 0.25 inches per hour. I got this answer by dividing 6 by 24 (6 is the dividend and 24 is the divisor).

Answer 2

A) 1 foot = 12 inches

0.5 foot x 12 inches = 6 inches per day

B) 1 day = 24 hours

 6 inches / 24 hours = 0.25 ( 1/4) inch per hour
