b) 540 mph

c) speed of the wind = 49.1 mph

Step-by-step explanation:

Given that flight between Joppetown and Jawsburgh took 5 hours and 30 minutes.

Speed = 2700/5.5

Speed = 490.91 mph

The return flight took 5 hours of the same distance from = 2700 miles

Speed = 2700/5 = 540 mph

speed of the wind = the difference in the two speed

speed of the wind = 450 - 490.91

speed of the wind = 49.1 mph

Speed = 540m/s
