Answer:
Plain still in air = 240
Air current = 28
Step-by-step explanation:

The speed of the small jet is 268mi/hr
The speed of the tallwiind is 212mi/hr
The formula for calculating the speed is expressed as:
Speed = Distance/Time
For the small jet:
Speed = 1072/4
Speed = 268mi/hr
Hence the speed of the small jet is 268mi/hr
For the tall wind:
Speed = 848/4
Speed = 212mi/hr
Hence the speed of the tallwind is 212mi/hr
