13.5/3 = 4.5
He hiked for 4.5 hours.
<h2>Hello!</h2>
The answer is:
The first measurement of volume is equal to 835.23 mL.
<h2>Why?</h2>
Boyle's Law equation can be used when the temperature is kept constant, and it establishes a relation between the pressure and volume, showing that when an ideal gas is kept constant, the pressure and volume are inversely proportional.
So, we Boyle's Law equation states that:

Where,

Now, if we are looking for the first volume measurement, we need to rewrite the equation as follow:

So, substituting the given information and calculating, we have:


Hence, the first measurement of volume is equal 835.23 mL.
Have a nice day!
Y= arcsin(x) is equivalent to sin(y) = x
we know that -1≤x+1, hence the range of y is: -π/2≤y≤+π/2
