A plane flew 1740 km in 6 hours with tail wind. On return trip, going into the wind, the plane flew 570 km in 3 hours. What is the planes speed if there was no wind.
----------------
1740 km/6 hr = 290 km/hr
570 km/3 hr = 190 km/hr
-------------
The plane's airspeed is the average = 240 km/hr
-----------------
The term is airspeed, and planes don't use kilometers.
They use nautical miles and knots.
