Aplane travels at a speed of 205mph in still air. flying with a tailwind, the plane is clocked over a distance of 1000 miles. flying against a headwind, it takes 2 hours longer to complete the return trip. what was the wind velocity? (round your answer to the nearest tenth.)

While plane is moving under tailwind condition it took time "t"

so here we will have

here net speed of the plane will be given as

similarly when it moves under the condition of headwind its net speed is given as

now time taken to cover the distance is 2 hours more

now solving two equations

solving above for v_w we got

answer; ///i believe that the correct answer is (carbon); good luck

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
