Question

A plane travels at a speed of 180 mph in still air. Flying with a tailwind, the plane is clocked over a distance of 725 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.)

Answer 1

you are endless
i always get these backwards
let me try and see if what i get makes sense

Answer 2

I only have 2 or 3 more!

Answer 3

Hopefully they are easy! :)

Answer 4

i solved \[\frac{725}{180+x}=\frac{725}{180-x}+2\] but i got an answer that made no sense

Answer 5

let me think about why it is wrong

Answer 6

I got 18.97. I don't think mine is right

Answer 7

with headwind rate is \(180+x\) so the time is \[\frac{725}{180+x}\]with the head wind

Answer 8

Right I did that part

Answer 9

maybe that was the tailwind
in any case that was with the wind not against is

Answer 10

against the wind the rate is \(180-x\) so the time is \(\frac{725}{180-x}\)

Answer 11

ooh i see how i screwed up

Answer 12

Yea and I subtracted them and set them equal to 2.

Answer 13

i did this \[\frac{725}{180+x}=\frac{725}{180-x}+2\] but it should have been this \[\frac{725}{180+x}=\frac{725}{180-x}-2\]

Answer 14

and got \(x=42.23\) which makes a lot more sense

Answer 15

Yes it does!

Answer 16

your math teacher must hate you

Answer 17

I am taking prep for college math. I finished 3 semesters of work in 2 semesters but I had to get a little extension on the last part. She actually loved me because I tried!

Answer 18

i am sure
i just meant giving all these annoying word problems

Answer 19

Yeah. Well it is online so she has no choice haha!

Answer 20

I have been doing this math for 6 hours now. I am ready to be done!
