Answer:
The maximum speed of Hal's airplane in still air is:
The speed of the wind
Step-by-step explanation:
Remember that the velocity v equals the distance d between time t.
and
The distance that Hal travels when traveling with the wind is:
miles
Where v is the speed of Hal and c is the wind speed.
The distance when traveling against the wind is:
miles
Now we solve the first equation for v
Now we substitute the value of v in the second equation and solve for c
Then:
The maximum speed of Hal's airplane in still air is:
The speed of the wind
