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
