Pressure is inversely proportional to volume (at constant temperatures.)
Reducing the volume of a container will increase the gas pressure inside because there will be more collisions of the gas particles with the walls of the container.

Answer:
(a). The shortest length of highway is 79.21 Km.
(b). The angle is 31.0°
Explanation:
Given that,
The distance in south direction = 40.8 km
The distance in west direction = 67.9 km
(a). We need to calculate the shortest length of highway
Using Pythagorean theorem
(b). We need to calculate the angle
Using formula of angle
Put the value into the formula
The direction is south of west.
Hence, (a). The shortest length of highway is 79.21 Km.
(b). The angle is 31.0°
