the average of 200 and 160 is 180
so the speed of the plane with no wind is 180 mph,
and the wind speed is 20 mph
check:
going against the wind = 180-20 = 160
going with the wind = 180 + 20 = 200
so the speed of the plane with no wind is 180 mph,
and the wind speed is 20 mph
check:
going against the wind = 180-20 = 160
going with the wind = 180 + 20 = 200
