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
You need 3 numbers, divide the total by 3:
84/3 = 28
This is the middle value.
Now you use the one lower and the one higher:
27 + 28 + 29 = 84
The numbers are 27, 28, 29

Remove the flat rate to see how much money she has to spend: 10 - 1.95 = 8.15.
We have 8.15 (remaining money) / 0.60 (per mile) = 13 miles (or <span>13.5833333333 [copy pasted from a calculator moderators] but I assume you want a rounded version)</span>
