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.
Answer:
You keep them if you test 3 and all pass.
There are 18 good ones and 6 bad (making 24)
Chance of first passing is 18/24
If it passes, there are now one less good and one less total.
Chance of second passing is 17/23
If it passes, there are now one less good and one less total.
Chance of second passing is 16/22
Total is (16 x 17 x 18) / (22 x 23 x 24) = about 0.4 (0.403162055 is you really want to know).
So probability all are ok is 0.4
Thus probability you find at least one bad one is 0.6
Hope this helps you out!
