Answer:
The speed of George the Pigeon in still air = 21 miles/hr
The speed of air = 3 miles/hr
Step-by-step explanation:
Let the speed of George the Pigeon in still air =
miles/hr
Let the speed of air =
miles/hr
Distance traveled = 72 miles
Relative speed against the wind =
miles/hr
Time taken against the wind = 4 hours
Relative speed with the wind =
miles/hr
Time taken against the wind = 3 hours
Using the formula:



Adding (1) and (2):

By equation (1):

Therefore, the answer is:
The speed of George the Pigeon in still air = 21 miles/hr
The speed of air = 3 miles/hr
