R = rate of growth of raindrop vine = 0.75 feet/day
we know that : 1 feet = 12 inches
1 day = 24 hours
replacing the units accordingly in the above expression for rate of growth of raindrop vine
R = 0.75 (feet/day) (12 inches/1 feet) (1 day/24 hours)
R = (0.75 x 12 /24) (inches/hour)
R = 0.375 inches/hour
Answer: 78
