**1. The problem statement, all variables and given/known data**

If the pressure reading of your Pitot tube is 17.0 mm Hg at a speed of 150 km/h, what will it be at 700 km/h at the same altitude?

**2. Relevant equations**

The only eq I could think if is p = p_{2}+ 1/2 density (v_{2}^2 – v_{1}^2)

But I don’t know the density

**3. The attempt at a solution**

So I pretty much get stuck in the beginning, any help will be nice

Thanks
