The temperature at 9 am was -11 degrees.
We know that at 5 am, it was -7 degrees. Since the change of temperature is a negative number, then we subtract the absolute value of the change from -7. -7 - 3 = -10. Following this pattern, we then have:
-10 - 2 = -12 (6 am - 7 am)
-12 - 5 = -17 (7 am - 8 am)
-17 + 6 = -11 (8 am - 9 am, added since it was a positive change of temperature)
And our final answer is -11 degrees Fahrenheit.

Answer: a) 490.91 mph
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.
Time t = 5.5hours
Distance = 2700 miles
Speed = distance/ time
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
