Tofind:the rate of plane with wind and against wind.
Answer to Problem 3OE
The rate of the plane with the wind is
Explanation of Solution
Given:
Concept used:
If the plane is with the wind then it’s taken as
If the plane is against the windthen it’s taken as
If the direction of plane is with the wind means planemakes
The resultant will be:
Similarly,
If the direction of plane isagainst the wind means plane make
Calculation:
If the rate of the plane in still air is
1.The rate of the plane with the wind is:
The rate of the plane against wind is:
If the rate of the plane in still air is
2.The rate of the plane with the wind is:
The rate of the plane against wind is:
If the rate of the plane in still air is
3.The rate of the plane with the wind is:
The rate of the plane against wind is:
If the rate of the plane in still air is
3.The rate of the plane with the wind is:
The rate of the plane against wind is:
Hence the table is
Rate of plane in still air | Rate of wind | Rate of plane with wind | Rate of plane against the wind |
Hence, the rate of the plane with the wind is
