Question 1206064: With a tailwind, an aircraft can fly 408 miles in 3 hours.
Against this same wind, the aircraft can fly the same
distance in 4 hours.
Find the effect of the wind and the average airspeed
of the aircraft.
Answer: The impact of the wind resistance on the
aircraft is ?
and the average airspeed of the aircraft is ?

With a tailwind, an aircraft can fly 408 miles in 3 hours. Against
this same wind, the aircraft can fly the same distance in 4 hours.
Find the effect of the wind and the average airspeed of the aircraft.


             A = average airspeed of plane
             w = speed of wind

             | DISTANCE |   RATE  |  TIME | 
with wind    |   408    |   A+w   |   3   |     
against wind |   408    |   A-w   |   4   |

             

             
 
         Divide 1st equation by 3, 2nd equation by 4:

             

        Add the two equations:

             
             

         Air speed = 119 mph

         Subtract the two equations:

             
             

         Wind speed = 17 mph
