Answer:
18/5 hours
Step-by-step explanation:
If Vera's phone has a battery life of 2/5 and it drains 1/9 every hour we can determine how much per hour her battery drains.
f the battery drains 1/9 per hour we know how much it drains per hour. To get the time is takes for 2/5 battery life to drain we can say 2/5 divided by 1/9.
We have 5 and 1 at the bottom of the line and 9 and 2 at the top of the line. We can simplify:
It takes 18/5 hours for Vera's battery to last

So is doubling, first off, meaning, if the current amount say P, then when it doubles is 2P, or double that, or P + P, so the rate of growth is 100%, since it's doubling.
and is doing it every 9 hour cycle, thus
