How long will a plane have to fly continuously with 1100 miles per hour in order to cover the same distance as that from earth to the next star, proxima centauri?

Explanation :

It is given that,

Velocity of plane, v = 1100 mi/h

Proxima Centauri is a red dwarf star. Its distance from Earth to  Proxima Centauri is 4.243 light year.

Or we can say that the distance between Earth and  Proxima Centauri is,

We know that, time

or

t = 2.5 years ( approx )

Hence, this is the required solution.

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
