Question

a vine called the mile-a-minute weed is known for growing at a very fast rate. it can grow up to 0.5 ft per day. how fast in inches per hour can the mile-a-minute weed grow up to?

1 feet equals 12 inches
0.5 feet, therefore, is 6 inches. 
but that is per day, so divide that by 24, which results in 1/4 inches per hour.
