Water rises inside a plant's stem an average of 4ft. every hour.

Question

A. How many inches is that? The answer for this is 48 inches.
B)If a plant is 72 in. tall, how long would it take for water to travel from the bottom to the top of the plant?
On part B, I didn't understand on how to get the answer. Please help

Answer 1

B.

It travels 48 inches in one hour.

72 - 48 = 24

24/48 = 1/2

So it would take an hour and a half to reach the top of a 72-inch plant.

Answer 2

90 minutes
