Answer 1

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
