Reminder Round all answers to two decimal places unless otherwise indicated.
Airspeed The airspeed of a plane is its speed in the absence of wind. With a headwind, ground speed (the actual speed in relation to the ground) is decreased by the speed of the wind. With a tailwind, ground speed is increased by the speed of the wind. Let
a. Express the ground speed on the trip out in terms of
b. Use the information from part a and the fact that distance equals rate times time to find an equation involving
c. Express the ground speed on the return trip in terms of
d. Use the information from part c and the fact that distance equals rate times time to find an equation involving
e. Find the airspeed and the speed of the wind.
