a jet can travel 1200 km distance in 12 hours with the wind. the return trip against the same wind takes 15 hours. Find the rate of the jet in still air and the rate of the wind
------------
1200/12 = 100 km/hr
1200/15 = 80 km/hr
-----------
Airspeed = that average = 90 km/hr (that's some fast jet, you can look down as see cars going faster)
Windspeed is the differenc = 10 km/hr
