A plane flying a its maximum speed can go 200 miles per hour with a tailwind and 160 miles per hour into a head wind.

a) What is the wind speed?
b) What would the maximum speed of the plane be if there was no wind?

1 answer

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
