Answer:
The speed of the private airplane is 770 mph, the speed of the commercial airplane is 980 mph.
Step-by-step explanation:
Let x mph be the speed of private airplane. If the speed of the commercial jet is 210 miles per hour faster than the speed of the private airplane, then the speed of commercial airplane is (x+210) mph.
It takes the commercial jet 1.1 hours for the flight, then it covered the distance of
It takes the private airplane 1.8 hours for the flight, then it covered the distance of
The distances are the same, so
The speed of the private airplane is 770 mph, the speed of the commercial airplane is 770 + 210 = 980 mph.

Step-by-step explanation:
To determine the time it takes for the ball to hit the ground, we need to figure out when 
.
Separating this into two separate equations will give us the times that :
We can ignore since that is the initial time that the ball is kicked from the ground, so the answer to the question is .
