An airline runs a commuter flight between Portland, Oregon, and Seattle, Washington, which are 145 miles apart. An increase of 2
pychu [463]

The speed of the airplane is the ratio of the distance to the time

The initial average speed of the airplane is approximately 110.8 mph

Reason:

Given parameters are;

The distance between Portland Oregon and Seattle Washington = 145 miles

The decrease in travel time when the speed is increase by 20 mph =  minutes

The initial speed of the airplane, v = Required;

Solution;

t = \dfrac{145}{v}

t - \dfrac{12}{60}  = \dfrac{145}{v + 20}

Therefore;

\dfrac{145}{v} - \dfrac{12}{60}  = \dfrac{145}{v + 20}

Which gives;

\dfrac{145}{v + 20} - \dfrac{145}{v} + \dfrac{12}{60} = 0

Therefore

0.2·v² + 4·v - 2,900 = 0

v ≈ ±110.8 mph

The initial average speed of the airplane, v≈ ± 110.8 mph
