u said airspeed remains the same, so 840 mi in 3 hrs the groundspeed is 280, for the return trip groundspeed is 240, therfore the wind speed is 40
360 km/h
The jet will overtake the airplane in 0.5 hours.

275 km/hr
Call the airspeed of the airplane 'A', and the wind-speed 'W'.A - W = 500A + W = 600Add the two equations . . . . . 2A = 1,100Divide each side by 2 . . . . . . A = 550Substitute that resultinto the first equation . . . . . 550 - W = 500Add 'W' to each side . . . . . . 550 = 500 + WSubtract 500 from each side . . 50 = WThe aircraft is capable of 550 km/hr airspeed.The wind's speed is 50 km/hr.

If 4 hours return seven then 6 hours has return in 4 hours and 2 more hours will no return within 4 hours.

About six hours by airplane.
The plane's airspeed is the sum of its speed relative to the air and the speed of the jet stream. To calculate the plane's airspeed when traveling with the jet stream, we can subtract the jet stream speed from 1150 miles divided by 5 hours. This gives an airspeed of 230 miles per hour.
