Answer:
x = -5.83, -0.17
Step-by-step explanation:
Quadratic Formula: 
Since we are given <em>a</em> = 1, <em>b </em>= 6, and <em>c</em> = 1 from our quadratic, we use the Quadratic Formula:
Step 1: Plug in variables

Step 2: Solve


Step 3: Evaluate to decimals
When you do so, you should get x = -5.82843 and -0.171573
Let t represent the # of hours required for the west-east flight.
Then (540 mph)(t) = 2700 miles, and t = 5 hours. Flying east-west should take 1 hour less, or 4 hours.
This east-west speed would be 2700 miles / 4 hours = 675 mph (answer)
