A person walks first at a constant speed of 5.50 m/s along a straight line from point circled A to point circled B and then back along the line from circled B to circled A at a constant speed of 2.85 m/s. (a) What is her average speed over the entire trip? 3.9 Incorrect: Your answer is incorrect..

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.
