Computing Wind Speed The average airspeed of a single engine aircraft is 150 miles per hour. If the aircraft flew the same distance in 2 hours with the wind as it flew in 3 hours against the wind, what was the wind speed?
To find: The average airspeed of a single- engine aircraft is 150 miles per hour. If the aircraft flew the same distance in 2 hours with the wind as it flew in 3 hours against the wind, what was the wind speed?
Answer to Problem 62AYU
The average wind speed is 30 mph.
Explanation of Solution
Given:
The average airspeed of a single- engine aircraft is 150 miles per hour. The aircraft flew the same distance in 2 hours with the wind as it flew in 3 hours against the wind.
Calculation:
Let the distance be .
It is given that average airspeed is 150 miles per hour.
For with the wind is given by,
We have, .
For against the wind is given by,
We have, .
Average Airspeed .
For with the wind is given by,
For against the wind is given by,
Average wind speed .
Therefore, the average wind speed is 30 mph.
