Answer:
Speed of plane in still air = 825 km/h
Step-by-step explanation:
Given:
Speed of plane with the wind is 145 km/h faster than what it would have with still air.
Speed of plane with wind = 970 km/h
To find speed of plane in still air.
Solution:
Let speed of plane in still air be = 
km/h
Thus speed of plane with wind would be given as = 
km/h
Speed of plane with wind is given =970 km/h
So, we have:
Solving for .
Subtracting both sides by 145.
∴ 
km/h (Answer)
Thus, speed of plane in still air = 825 km/h

Answer:
The approximate temperature of the pan after it has been away from the heat for 9 minutes is 275.59°F.
Step-by-step explanation:
The formula for D, the difference in temperature between the pan and the room after t minutes is:
Compute the approximate difference in temperature between the pan and the room after 9 minutes as follows:
Then the approximate temperature of the pan after it has been away from the heat for 9 minutes is:
D = P - R
206.59 = P - 69
P = 206.59 + 69
P = 275.59°F
Thus, the approximate temperature of the pan after it has been away from the heat for 9 minutes is 275.59°F.
