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.

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.
8 hours
About six hours by airplane.
