Answer:
The answers are in the question.
Step-by-step explanation:
The wording can be off-putting but the answers are mostly there for you. It says that when the wind was at the tail of the plane, the travel was hastened to 5 hours instead of six. Is the rate of speed with the wind in favor of the plane is r+21, then it stands to reason that traveling AGAINST the wind will cause the rate to drop to r-21. Taking the average of the two travel times (5 and 6 hours each), we get 5.5 hours. Since speed is distance divided by time, the speed of the plane in still air will be <em>d</em> / 5.5
Be sure to label the speed as mph.

Step-by-step explanation: hope this helped
A fraction is just the easier, cleaner way of writing a division problem
the numerator is the number you are dividing
the denominator is the number you are dividing with
EX- 2 divided by 3 as a fraction is
2/3
A) =27.2
