Answer:</h2>
The speed of the commercial jet is while the speed of the private airplane is
<h2>
Step-by-step explanation:</h2>
Let's name the commercial jet as cj and private airplane as pa, so we know the following:
<u>It takes the commercial jet 1.1 hours for the flight, so:</u>
<u>It takes the private airplane 1.8 hours for the flight, so:</u>
<u>The speed of the commercial jet is 210 miles per hour faster than the speed of the private airplane:</u>
Let's name the speed of the commercial jet as and the speed of the private airplane as , then:
From physics we know that:
Since the distance from Denver to phoenix is unique, then:
Thus, from the equation and given the relationship we have:
Finally, the speeds are:
