As an airplane taxies on the runway with a speed of 16.5 m/s, a flight attendant walks toward the tail of the plane with a speed of 1.22 m/s. what is the flight attendant's speed relative to the ground?

The flight attendant's speed relative to the ground=15.28 m/s

Explanation:

speed of airplane with respect to ground=16.5 m/s

speed of flight attendant towards the tail of plane=1.22 m/s

since the plane and the attendant are moving in opposite directions,so

V=16.5-1.22

V=15.28 m/s

so the flight attendant's speed relative to the ground=15.28 m/s

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
