Question

2.2. 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? Show your work using the correct conversion factors

Answer 1

So 0.5 ft per day is the same as 0.5 ft per 24 hours. This equals 0.5/24 ft an hour. 0.5 ft /24=0,02083 ft. Simple conversion yields 0.02083*12=0.25. So the vine can grow by .25 inches per hour.

Answer 2

24h=1day 12inches=1ft

0.5/24 = 0.02083

0.02083*12= 0.25 inches per hour
