Let x be total hours of battery life. We have been given that battery life of Vera's phone is down to 2/5. So remaining battery life,

$1-\frac{2}{5}=\frac{5-2}{5}=\frac{3}{5}$

We have been also given that it drains another 1/9 every other hour. Now let us substitute our given information into an equation.

$\frac{1}{9}\cdot x=\frac{3}{5}$

Now we will solve for x.

$x=\frac{3\cdot 9}{5}=\frac{27}{5}$

$x=(5+\frac{2}{5})hours$

Let us convert 2/5 into minutes. We know 1 hour has 60 minutes.

$60\cdot \frac{2}{5}=24\text{minutes}$

Therefore, remaining battery life will be 5 hours and 24 minutes.

$(3+2)^2+(5+4)^2=x^2\\ 5^2+9^2=x^2\\ 25+81=x^2\\ x^2=106\\ x\approx10.3$
