Complete Question

The barometer of a mountain hiker reads 980 mbars at the beginning of a hiking trip and 790 mbars at the end. Neglecting the effect of altitude on local gravitational acceleration, determine the vertical distance climbed. Assume an average air density of 1.20kg/m^2

Answer:

h=1614m

Explanation:

From the question we are told that:

Initial Pressure P_1=980mbar=>98000Pa

Final Pressure P_2=790mbar=>79000Pa

Density \rho=1.20kg/m^2

Generally the equation for Height climbed is mathematically given by

h=\frac{P_1-P_2}{\rho*g}

h=\frac{P_1-P_2}{1.20*9.81}

h=1614m
